I'm trying to install OpenStack compute (nova) .. when I run command **nova list**
then out the results ERROR: You must provide a username via either --os_username or env[OS_USERNAME]
how to code a solution for me?
If you used devstack (http://devstack.org/) to deploy OpenStack you can use openrc trick:
$cd devstack/
$source openrc admin admin # for admin rights
or
$source openrc demo demo # for demo user
Otherwise you need to export OS variables manually:
$export OS_USERNAME = admin
$export OS_TENANT_NAME = <yourtenant>
$export OS_PASSWORD = <yourpasswd> # password which you used during deployment etc

If you want manually install all the services here's handy manual https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_MultiNode/OpenStack_Grizzly_Install_Guide.rst
I'd recommend to install it once by this manual to learn how it works, and then use latest stable devstack each time when you need to set up a new environment just to save your time.

to remove this error you just need to execute command
"source openrc"
where openrc is the file where in all the credentilas are stored .. make sure you have that file in the folder. You might also have name of the file something other than open but it ll end with rc .. just change the name according to your file
In my case I needed to call "source stackrc" and it fixed the problem.
I did the following to get rid of the error.
cd devstack
. openrc #this will setup the environment
the below command is used to get access right of "admin" and use the project "admin"
. openrc admin admin

Setup
I'm following the installation directions in the mirthSync readme, which is to clone the repo. The next indication of usage that I can see is in the Examples section, which via CLI is to "pull Mirth Connect code from a Mirth Connect instance":
java -jar mirthsync.jar -s https://localhost:8443/api -u admin -p admin pull -t /home/user/
I'm assuming that after cloning the repo, one should cd into that directory and then run the java -jar... command with all the appropriate flag values (server, username, password, etc).
Error
After running the CLI command, I get this error:
Error: Unable to access jarfile mirthsync.jar
Question
Where is this mirthsync.jar file supposed to come from? Is there something I need to do in order to generate the mirthsync.jar file?
Generate it via lein uberjar (which creates target/uberjar/*-standalone.jar) or download it from a release.
I followed the Software Collections Quick Start and I now have Python 3.5 installed. How can I make it always enabled in my ~/.bashrc, so that I do not have to enable it manually with scl enable rh-python35 bash?
Use the scl_source feature.
Create a new file in /etc/profile.d/ to enable your collection automatically on start up:
$ cat /etc/profile.d/enablepython35.sh
#!/bin/bash
source scl_source enable python35
See How can I make a Red Hat Software Collection persist after a reboot/logout? for background and details.
This answer would be helpful to those who have limited auth access on the server.
I had a similar problem for python3.5 in HostGator's shared hosting. Python3.5 had to be enabled every single damn time after login. Here are my 10 steps for the resolution:
Enable the python through scl script python_enable_3.5 or scl enable rh-python35 bash.
Verify that it's enabled by executing python3.5 --version. This should give you your python version.
Execute which python3.5 to get its path. In my case, it was /opt/rh/rh-python35/root/usr/bin/python3.5. You can use this path to get the version again (just to verify that this path is working for you.)
Awesome, now please exit out of the current shell of scl.
Now, lets get the version again through this complete python3.5 path /opt/rh/rh-python35/root/usr/bin/python3.5 --version.
It won't give you the version but an error. In my case, it was
/opt/rh/rh-python35/root/usr/bin/python3.5: error while loading shared libraries: libpython3.5m.so.rh-python35-1.0: cannot open shared object file: No such file or directory
As mentioned in Tamas' answer, we gotta find that so file. locate doesn't work in shared hosting and you can't install that too.
Use the following command to find where that file is located:
find /opt/rh/rh-python35 -name "libpython3.5m.so.rh-python35-1.0"
Above command would print the complete path (second line) of the file once located. In my case, output was
find: `/opt/rh/rh-python35/root/root': Permission denied
/opt/rh/rh-python35/root/usr/lib64/libpython3.5m.so.rh-python35-1.0
Here is the complete command for the python3.5 to work in such shared hosting which would give the version,
LD_LIBRARY_PATH=/opt/rh/rh-python35/root/usr/lib64 /opt/rh/rh-python35/root/usr/bin/python3.5 --version
Finally, for shorthand, append the following alias in your ~/.bashrc
alias python351='LD_LIBRARY_PATH=/opt/rh/rh-python35/root/usr/lib64 /opt/rh/rh-python35/root/usr/bin/python3.5'
For verification, reload the .bashrc by source ~/.bashrc and execute python351 --version.
Well, there you go, now whenever you login again, you have got python351 to welcome you.
This is not just limited to python3.5, but can be helpful in case of other scl installed softwares.
When I create a new project and select to create a new Git repository, or when I try to change the version control system in project options I receive a RStudio error stating "Incorrect function" with a big X and no extra information.
The below link has a similar issue, but their solution of changing the path for git.exe has not helped (i have tried all three paths)
https://support.rstudio.com/hc/en-us/community/posts/200632528-Git-Error-Incorrect-Function
Some extra notes:
RStudio allows me to clone repository to set new working directory
Also git works in bash, so i feel this is an RStudio issue.
I encountered the same error. For me it also had to do with using a network path not a local directory for the project location (as for lewis1211).
Workaround: Map the network drive. E.g. Map your //server/share to some drive, say Z: (using map network drive, if you are using windows). If you set your project up under Z: then, it works.
If you have already chosen "git.exe" in RStudio --> Tools --> Global Options --> Git/SVN, then try to open Rstudio shell and type git init. In my case it showed "Permission denied", and after running as administrator the problem has gone.
This is only a partial answer if it fixes your problem: I reproduced this when trying to use a network path for a project location. When using a local directory no error occurs. Could indeed be an RStudio issue.
Run you R studio as Project administration.
This solves my issue.
SOLVED.
I had the same problem. The Git-RStudio-Connection fails but git is working perfectly in the CMD. When running the git init command in CMD it works and creates a .git folder. But running the git init command in the RStudio terminal fails with a message Warning: unable to access 'C:/Users/%username%/.gitconfig': Permission denied ... fatal: unknown error occured while reading the configuration files.
The Version Control Sytem (VCS) or git-Panel does not appear in RStudio and selecting it in the projects options leads to the same message Error: Unzulässige Function (eng. Error: Incorrect function).
A closer look into the .gitconfig file should give you a new solution approach hopefully without having administration rights. Comparing the installation on the integration worksation with a productive workstation shows, that on the Test-Machine an incomplete .gitconfig file is on C:/Users/%username%/.gitconfig and on the Productive-Machine a complete gitconfig file is on Z:/.gitconfig. By the way, Z is a mapped drive which is linking to the company's user-profile settings (see CMD > echo %HOMEDRIVE%).
According to this analysis there should be multiple possible solution approaches:
(1) delete the corrupt .gitconfig and hope the the system is correctly looking into your profiles directory
(2) complete the .gitconfig file that all necessary information are there. The message fatal: unknown error occured while reading the configuration files could actually be a hint, that the first message access... permission denied is false and the problem lies in the incomplete file.
(3) Be aware that there can be a confusion between ".gitconfig" as FILE and ".gitconfig" as FOLDER. Check this with changing directory with cd to folder and cat to show the file content. It will tell you that you cannot display a folder as file-content.
(4) Change the location of the config file with git config --file FullnameToGitconfig. e.g. git config --file %USERPROFILE%/.gitconfig or git config --file %USERPROFILE%/.gitconfig/gitconfig or git config --file %HOMEDRIVE%/.gitconfig etc.

When attempting to push to GitHub from RStudio, I get the following errors.
error: unable to read askpass response from 'rpostback-askpass'
fatal: could not read Username for 'https://github.com':
No such device or address
RStudio has my origin as
https://github.com/rmscriven/other.git
when it actually should be
https://github.com/rmscriven/saber.git
RStudio will not allow me to change the origin from the version control system. Here is what it shows:
Is it possible to change my GitHub origin url from RStudio?
Thanks to the pro tip provided by #krlmlr in the comments,
Use an empty target directory. Look for "clone URL" on your GitHub project page, perhaps choose the SSH variant.
I clicked "clone url" on GitHub once, nothing. Then again, nothing. And once again for good measure, nothing. So I went to the terminal, read the man git help file, and decided to change my password and reconfigure. These are the lines I ran, and it was successful.
git config --global user.name <myuser.name>
git config --global user.email <myuser.email>
git clone https://github.com/rmscriven/saber.git
git pull
Then I went to RStudio and it allowed me to clone my repository, and change the URL of my version control setting. Here's a colorful pic
New project -> Version Control -> Git -> Create Project
Next, magic happened, and I had a copy of my package which I very carefully removed to prepare to push the development tarball to GitHub. Rock on.
#krlmlr, I thank you for nudging me in the right direction. Now I feel like I'm actually doing it the right way. :)
And for fun, try saying 'rpostback-askpass' ten times fast.
I had the same problem and for me these two simple steps worked great:
Add the SSH key from RStudio to my github account.
Change the origin URL and use the -u flag for push/pull once (solution found here).
For 1., in RStudio go to Tools → Global Options... → Git/SVN → view public key, and copy the key. In your browser of choice, logged in on Github, click Edit Profile → SSH keys and paste the copied key here.
For 2., back in RStudio, click Tools → Shell… , then enter:
git remote add origin https://github.com/myname/test.git
git config remote.origin.url git#github.com:myname/test.git
git pull -u origin master
git push -u origin master
Of course, change "myname" to your username and "test.git" to the name of your project. (Or even "github.com" to the URL of your institute's github or similar.)
After doing this once, the Push/Pull buttons in RStudio should work and you don't need the shell anymore!
I've been running into this issue on multiple computers now, with a remote that doesn't support SSH and thus can't leverage password-less login.
The problem in this case is that by default, git ask for the password interactively, and RStudio can't display this graphically. The trick is to use git's credential storage system.
For instance on Mac OS X:
git config --global credential.helper osxkeychain
On Linux one could use the gnome-keyring integration.
I installed Hadoop and Created a user named hduser and changes owner of hadoop folder to hduser.
After installing Hadoop i try to execute the hadoop command to check whether it is installed or not but it is giving "hadoop" command not found.
Then i had given execute privilege to hduser on all the files inside hadoop folder include bin folder
But still output is same.
When i am trying the same hadoop command with root as a user its working fine.
I think it is related to unix commands. Please help me out to give my user the privilege to execute hadoop command.
One more thing if i switch to root then hadoop commands works fine.
It is not a problem of privileges. You can still execute hadoop, if you type /usr/local/hadoop/bin/hadoop, right?
The problem is that $PATH is user-specific.
You have to add your $HADOOP_HOME/bin to the $PATH, as hduser, not as root. Login as hduser first (or just type su hduser) and then export PATH=$PATH:/$HADOOP_HOME/bin, as #iamkristian suggests, where $HADOOP_HOME is the directory in which you have placed hadoop (usually /usr/local/hadoop).
I sounds like hadoop isn't in your path. You can test that with
which hadoop
If that gives you command not found the you probably just need to add it to your path. Depending on where you installed hadoop, you need to add this to your ~/.bashrc
export PATH=$PATH:/usr/local/hadoop/bin/
And then reopen your terminal
