Riak not starting - riak

I have installed riak and erlang as mentioned in the basho website.
But when i try to start riak with the command:
/etc/init.d/riak start
or
service riak start
I get the following error:
Starting Riak: Riak failed to start within 15 seconds,
see the output of 'riak console' for more information.
If you want to wait longer, set the environment variable
WAIT_FOR_ERLANG to the number of seconds to wait
I also checked with the command: riak ping, which gave the error:
Attempting to restart script through sudo -H -u riak
Node 'riak#sys_ip' not responding to pings
I am using 64 bit Centos 6.3 machine. Can anybody help me with this?
Initially when i had installed riak and checked the status, it showed that riak had started. Somewhere during the experimentation, it has stopped working. Not able to find, as to what might be the reason?
Thanks

Thanks all ! I found the solution to my problem. I was running the commands as root user. When I tried using the same commands as non-root user with sudo prefix, everything just worked fine ! :)

Try running following command, it runs diagnostic test over configuration settings and gives more verbose information if there is anything wrong.
riak console
riak start by default doesn't give verbose information about the issue. In my case issue was - missing write permissions on directory - /var/lib/riak/generated.configs.

As you didn't mention any version of Erlang, I would like to inform you that using Erlang R15B02 causes error with riak-admin status.It's better to use Erlang R15B01 with Riak 1.2 and 1.2.1. Riak 1.0 requires Erlang R15B03 and later versions.So, check whether you have installed compatible versions.And if that's not the issue, here is the same issue as yours. Riak - Riak failed to start within 15 seconds,

How do I fix the CondaHTTPError [duplicate]

I'd like to install the pymongo library but I'm getting the following error:
(C:\Users\xxxxxxx\AppData\Local\Continuum\anaconda3) C:\Users\xxxxxxx>
conda install -c anaconda pymongo
Fetching package metadata ...
CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://conda.anaconda.org/a

A number of posts online simply reinstalled Anaconda, any other options apart from a fresh install?
This works a charm:-
Just copy these:-
libcrypto-1_1-x64.dll
libssl-1_1-x64.dll
from D:\Anaconda3\Library\bin to D:\Anaconda3\DLLs.
Execute the following command in the cmd prompt/terminal:
conda config --set ssl_verify no
I try to create a virtual env with python 2.7 with anaconda, the base env is python 3.7. I encounter the exactly same problem. It turns out that there isn't such problem with other virtual envs with python 3.7 or 3.6.
This post works perfectly to solve my problem on win7 with anaconda prompt.
It basically says you need to add the following directories into your user environment path in windows (go to Start and type in: View Advanced System Settings, then select Environmental Variables: then select Path and click Edit: finally you can click New and add a path):
C:\your_directory_to_anaconda3\Anaconda3\Scripts
C:\your_directory_to_anaconda3\Anaconda3\
C:\your_directory_to_anaconda3\Anaconda3\Library\bin -- This is the directory for openssl
If you added conda to your PATH variables, remove it and use the "Anaconda Prompt". This solved the problem for me.
See: https://github.com/conda/conda/issues/8046#issuecomment-450582208
I faced this issue when I tried to create environment. I solved it by first activating conda base environment by using:
conda activate base
then I created the environment
conda create -n myenv python=3.7
Check the proxy URL
Verify .condarc file
For me, the problem was with the indentation in the .condarc file.
proxy_servers:
http: http://testproxy:8080
https: https://testproxy:8080
My authenticated proxy server is configured with a domain whitelist for massive and repeated downloads so root or local sudoer doesn't need to be authenticated.
Adding conda.anaconda.org is not enough as this repo redirect its traffic to amazonaws.com.
In my case, adding ".amazonaws.com" to the whitelist solved the issue.
The issue was resolved by adding a username and password to file C:\Users\xxxxx.condarc
channels:
- defaults
ssl_verify: false
proxy_servers:
http: http://xxxxx:password#sproxy.fg.abc.com:yyyy
https: https://xxxxx:password#sproxy.fg.abc.com:yyyy
I had the same problem on Windows 10-64 bit and intuitively installed the 64-bit version of miniconda. However, it results in exactly the same error above. Installing 32 bit conda installer has resolved the issue
Before installing some package (pydicom) the installation run just fine. After
it I tried to install matplotlib, but I got the same error as yours.
I tried conda config --set ssl_verify no but it didn't solve the problem so I set it again to true.
Fortunately, I had a virtual environment where I installed my packages. I closed all Anaconda prompts and tried in a new test environment. Magically, the install worked. I came back to my original virtual env and run the install again, and it worked!.
It might be that I just had to wait for some time before I could use conda install again.
One other thing I could do is remove the package that caused the problem, but I didn't have the chance to try it. If it has anything to do with some virtual environments not being affected, then one possible way to guard against this is to clone the environment before installing any new package.
Edit: I tried the same solution but It did not work. But instead of showing the error immediately, it asks me whether I want to proceed. I deactivated the env, and re-opened anaconda prompt, then did the same steps as above and worked again.
I also had the Same Issue, I resolved by installing 32 bit Anaconda Installer.
Which resolved the CondaHTTPError: HTTP 000 CONNECTION, on Windows 64 bit.
I faced this issues after "conda clean -a" on win-64.
Activating and deactivating existing conda env resolved the issue.
You might need to upgrade your openssl installation
You can download it here (Try the latest version):
https://slproweb.com/products/Win32OpenSSL.html
Source:
https://github.com/ContinuumIO/anaconda-issues/issues/6424#issuecomment-464660808
My issue was simply not running the conda init command prior to attempting to create an environment.
Came across the CondaHTTP Connection error after installing Anaconda environment on a new Windows 10 computer. I tried virtually all the recommendations above unsuccessfully! Looking up the Anaconda archives ( https://repo.continuum.io/archive/ ), I downloaded the immediate previous release .... and on installation and rebooting my PC, all is now wellscreenshot of release
In short - installing Microsoft Visual C++ Redistributable for Visual Studio solved my problem.
In more detail: upon trying a suggested solution of installing a new version of OpenSSL, the installation process told me I was missing a dependency - the Visual Studio Redistributable package. The installer led me to a direct download page of the 2017 version. I can't find that page now, but the official release of 2019 can be found here, and should work as well (found under Other Tools and Frameworks).
Uninstalling and reinstalling anaconda for all users (instead, of current user only, requires admin privileges) and activating the option to add Anaconda to PATH during the installation process, fixed the issues for me.
Thank you everyone for your responses. In my case, I found out that my Kaspersky Internet Security was blocking it the whole time. The moment I quit the application all applications were downloaded. Please check your firewall settings before trying all the above options.
I tried all of these solutions and none worked for me. After running the command
conda config --remove-key channels
in the Anaconda Prompt, everything started working for me on my next attempt.
Adding that I had the same problem on ubuntu on WSL. None of the solutions worked for me, until I realized I was working on WSL version 1 (I thought I'd already upgraded). Upgrading from WSL 1 to WSL 2 solved the problem for me.
Running following these two commands worked for me.
conda config --remove-key proxy_servers
conda clean --source-cache
I'd tried all of the advice on this and many other webpages.
In the end I broadcast a "help me Obiwan Kenobi, you're my only hope message" to a large group of people at work and one of them who used python all the time was able to help me
The trick was to set several windows environmental variables
CURL_CA_BUNDLE
REQUESTS_CA_BUNDLE
SSL_CERT_FILE
To my company's root certificate (a .cer or .crt) which I had downloaded to a spot on my disk
You may also need to add (in my case)
C:\Users\kdalbey\Anaconda3\Scripts
(or your particular \Anaconda3\Scripts) to your path.
And then I set proxies just for good measure
note I previously copied libcrypto-1_1-x64.dll, libcrypto-1_1-x64.pdb, libssl-1_1-x64.dll, libssl-1_1-x64.pdb from anaconda3\Library\bin to anaconda3\DLLs so that could be part of the secret sauce
and it didn't work until I killed and restarted anaconda-navigator
Two steps to deal with this error.
The Anaconda prompt configures the path, to include all the necessary executable files (for instance Library\bin - On Windows, launch it with admin permission). So that you need to use it to execute conda :
Update conda with conda update conda
Exit my proxy software which solved the issue.
I would like summarize some of the proposed answers in this post and propose my experience on that. As it can be understood from the error explanation, the error is related to the connection and I strongly believe that no need to uninstall and reinstall anything if the real cause of the problem be known. My problem gone away after the system powered off and powered on again one day later. So, some possible causes and their solutions (these solutions could be tested in order based on the written bulleted order) could be as follows:
Crash in anaconda prompt:
Probable solutions:
Deactivating and activating the environment, without removing all packages or …, or
Closing/reopening the prompt (Michael Heidelberg) or
Using cmd.exe instead, perhaps
Non-responsiveness of the anaconda site:
Massive site traffics related probable issues, that could be the reason of non-responsiveness or to temporary block some IPs
Probable solutions:
Retying as recommended in the error: HTTP errors are often intermittent, and a simple retry will get you on your way. It solves my problem sometimes. or
Activate or deactivate VPNs or Proxies (like use in .condarc; see: Github sroder, Nandhan Thiravia, Vinod Sangale, Peter Lucas, Sunding Wei).
Try after a while if you have time
System firewall block the site:
That might be happened by activating and deactivating of VPNs, repeatedly or by some other works
Probable solutions:
Finding the issue in system firewall and allowing the connection in the firewall settings (ScienceJedi, Github)
Reboot, perhaps
If the aforementioned ways didn't solve the problem, testing the related answers in the following order:
Add ...\Anaconda3\Scripts, ...\Anaconda3\, and ...\Anaconda3\Library\bin to the path (talentcat, skerjj, Victor Ochieng, jankap), perhaps need a reboot after (lightarrow)
Copying libcrypto-1_1-x64.dll and libssl-1_1-x64.dll from D:\Anaconda3\Library\bin into D:\Anaconda3\DLLs (Swapnil)
I think it could be used in the first step because It is unlikely to be cause of any other problem. The reason I didn't mention this at the beginning is that the developers could placed these files in that directory during installation, too, in default, but they didn't; perhaps it had some reasons (Github).
Note: these files are for Python >3, and I didn't find them for Python 2. Perhaps they have another names.
It must be said that my problem didn't solve by this solution.
Keep your SSL stack up-to-date (kamal dua, Anaconda troubleshooting, update openssl, Abdulrahman Bres, Update to openssl 1.1.1)
I didn't recommend it at first because Its not a good idea to unset ssl verification unless you know what you are doing (Pratyush comment) and somewhere I read that it couldn't return to True again.
It must be said that my problem didn't solve by this solution, too.
conda config --set ssl_verify false
conda update openssl ca-certificates certifi

Getting error "you must have a tty to run sudo" when we run through Pentaho

I am getting a you must have a tty to run sudo error when I run a shell script with a R script in it.
Weird thing is, it doesn't happen every time. I think it is because of RAM issue, but I am not sure.
This means that you are running on a Linux distribution with 'sudo' configured to require a tty.

Automounting riofs in ubuntu

I have several buckets mounted using the awesome riofs and they work great, however I'm at a loss trying to get them to mount after a reboot. I have tried entering in the following to my /etc/fstab with no luck:
riofs#bucket-name /mnt/bucket-name fuse _netdev,allow_other,nonempty,config=/path/to/riofs.conf.xml 0 0
I have also tried adding a startup script to run the riofs commands to my rc.local file but that too fails to mount them.
Any idea's or recommendations?
Currently RioFS does not support fstab. In order to mount remote bucket at the startup time, consider adding corresponding command line to your startup script (rc.local, as you mentioned).
If for some reason it fails to start RioFS from startup script, please feel free to contact developers and/or fill issue report.
If you enter your access key and secret access key in the riofs config xml file, then you should be able to mount this via fstab or an init.d or rc.local script ..
See this thread
EDIT:
I tested this myself and this is what I find. Even with the AWS access details specified in the config file, there is no auto-matic mounting at boot. But to access the system, all one needs to do is to issue mount /mount/point/in-fstab .. and the fstab directive would work and persist like a standard fstab mounted filesystem.
So, it seems the riofs system is not ready at that stage of the boot process when filesystems are mounted. That's the only logical reason I can find so far. This can be solved with an rc.local or init.d script that just issues a mount command (at the worst)
But riofs does work well, even as the documentation seems sparse. It is certainly more reliable and less buggy than s3fs ..
Thanks all,
I was able to get them auto-mounting from rc.local with the syntax similar to:
sudo riofs --uid=33 --gid=33 --fmode=0777 --dmode=0777 -o "allow_other" -c ~/.config/riofs/riofs.conf.xml Bucket-Name /mnt/mountpoint
Thanks again!

Riak - Riak failed to start within 15 seconds,

Despiste deceptively easy to follow riak install instructions for ubuntu, I get the below error.
service riak start
Riak failed to start within 15 seconds,
see the output of 'riak console' for more information.
If you want to wait longer, set the environment variable
WAIT_FOR_ERLANG to the number of seconds to wait.
1) I updated the ip address in vm.args and app.config file and restarted riak
2) I ran the below:
riak-admin reip riak#xxx.xxx.xxx.xxx
Attempting to restart script through sudo -u riak
Usage riak-admin reip <old_nodename> <new_nodename>
What is are the riak docs telling me from https://wiki.basho.com/Basic-Cluster-Setup.html?
see the output of 'riak console' for more information.
Was there anything in 'riak console' worth sharing?
Usage riak-admin reip
This takes two arguments. It looks like you've only supplied one.
Feel free to pop into #riak on freenode if you want some realtime assistance.
This worked for me http://comments.gmane.org/gmane.comp.db.riak.user/9102
It is a RIAK packaging problem, you have to delete the ring folder for RIAK node(s) and restart again.
I had the same issue, it turned out to be that I had forgotten to install libssl0.9.8.
Try using these commands:
sudo apt-get install libssl0.9.8
sudo service riak restart
With earlier versions it is not even possible to install Riak without having libssl0.9.8, but in the latest version 1.2.0 I did not see any dependency warning and Riak starts as long as you only bind to 127.0.0.1. At least that is what I observed, the actual root cause might be something else.
Good luck!
If you're using (currently the latest) Riak 1.1.4, try pulling down the previous 1.1.2 version.
I had the same error and tried various combinations of Erlang and Riak versions; going to an earlier version of Riak seemed to do the trick.

Java program doesn't start on Unix machine

When I start Java application from command line on AIX 6.1 machine the application just doesn't start. All I get is a blinking cursor, hitting CTRL+C doesn't help. It seats in the list of processes all the time.
Even running the following command produces the same result so I don't think it is program related.
java -version
Cursor is blinking on the next line and nothing happens. When I open second session and type
ps -ef
I get the following:
tomcat 32243914 31850686 0 13:50:27 pts/7 0:00 -ksh
tomcat 5439538 32243914 1 13:50:50 pts/7 0:00 /usr/java6/jre/bin/java -version
On Windows my program runs just fine. So I think it is JRE or Unix related.
I'm not a Unix expert so I would appreciate any suggestions on how to trouble shoot this.
sounds strange , it seems that your process does not give hands back... No return
Do you have top binary installed on your AIX machine ?
Could you check that this machine follows the long list of requirements to run the java binary ? You may find useful information on the IBM java package webpage I guess...
Do you have lsof binaries or any other standard debuging tool ? lsof would point to any problem related to your AIX machine

We have an intermittent similar issue with Java on Solaris. Sometimes rebooting the machine helps. Other times we have to remove the .java file from the user's home directory. Very random and annoying. The box can be up for months before it happens, or mere hours...
