The user hdfs is missing in its own group - cloudera

I recently installed Cloudera and after doing installation, I ran the host inspector. But I saw some messages in it (screenshot attached). Please let me know how to get rid of them. Also, is the cluster good to use?
I have installed cloudera using root user.

ACORE API, assistance with errors and deployment

I'm having trouble with setting up ACORE API's and then having them work on a website.
Background:
Azerothcore running 3.3.5 on a debian standalone server, this has the Database, Core files and runs both the world and auth server basically a standard setup that is shown in the how-to wiki.
I also have a standalone web server, on the same subnet, but it's a separate server running linux and normal web server stuff, this has a wordpress installation with azerothcore plugin for user signup etc.
I'm trying to add the player map (https://github.com/azerothcore/playermap) and the ACORE-API set of functions (server status, arenastats, BG que and wow statistics) (https://github.com/azerothcore/acore-api)
Problem:
I understand the acore-api must be run in a container (docker or whatever) on the server, which I have done and it binds to port 3000, I can then go to the local ip:3000 and it brings up this error. (all db's etc are connecting and soap is working)
error 404 when navigating to IP:3000
I do get a few errors when running NPM install seen here: I'm not sure if they would be causing any issues or not.
screenshot of NPM errors on install
But further that, when I put say 'serverstatus' on the webserver (separate server) and configure the config.ts file I can't seem to get anything to display.
I'm not sure what I'm doing wrong but is the same scenario for all of the different functions for the acore-api
How are these meant to be installed and function? I feel I'm missing a vital step.
Likewise, with PLAYERMAP I have edited the comm_conf.php and set the realmd_id, but when loading the page, I do get the map, but the uptime is missing and no players are shown?
Could someone assist if possible?
Seems like an issue with NodeJS version. Update your NodeJS to latest LTS version 16.13.0 (https://nodejs.org)

Install Openstack on single node

I want to install Openstack on CentOS 8(single node). I am having single machine (physical machine) where I want to install all nodes of Openstack. This setup I required for simulation only not production use.
I have tried to install Openstack using packstac 3 times but couldn't success.
I got different issues during installation:
1.In first attempt After installation, I tried to create instance, but not getting console of instances even after it got created successfully.
2. In second attempt, during deployment of instance, network not getting allocated.
3. In third attempt, it got stuck at packstack, puppet testing only.
I have followed below 2 links:
https://computingforgeeks.com/install-openstack-victoria-on-centos/
https://www.google.com/amp/s/www.linuxtechi.com/install-openstack-centos-8-with-packstack/amp/
I followed each and every steps mention in the likns.
I want to create two Ubuntu VMs on Openstack.
Can someone provide me some links/video, where I can get everything which is required to install Openstack on single node and create two Ubuntu VMs and assign network to them and test the connectivity between these two VMS.
Thanks in advance.
I would use official Packstack documentation. Note that you should start with a totally fresh Centos installation; i.e. don't try to install Packstack on a server where a previous installation failed (or succeeded).
You can also try Devstack. Its default configuration requires a smaller machine than Packstack (in my experience, 8GB RAM should be sufficient). Same remark: Start with a fresh installation of Centos or Ubuntu.
Microstack is another alternative. Its advantage is a very simple and quick installation; its disadvantage is a very strange (in my opinion) configuration and not a lot of documentation. However, it is suitable for your purpose. It claims to work on any Linux, Windows and MacOS; it does require snap.
I suggest directly installation onto Ubuntu Server.
some time ago I wrote a serie of posts in which I explained in detail how to install OpenStack Rocky. The 2 first blog posts ([1] and [2]) contain commands, examples, content of configuration files that cover common scenarios and tips for the successful installation of most OpenStack services (keystone, nova, glance, etc.) in a single node, and the third post [3] describes the installation of a computing node. This 3rd post is installed in a different node for the sake of making it easier to understand how nova works, but the installation can be safely carried out in the same node than the other components.
I find that the posts are short enough and are very easy to follow (I use that blog as my installation tips, and so I have used them for several deployments). The only caveat is that it is based on Ubuntu, but if you know about your installation, it should be easy to translate the installation to CentOS (some colleagues have used these tips for CentOS installations).
I tried to install Openstack several times last week (october 2021): a) with CentOS 8 Stream to metal hardware (real server) with devstack - no one version was installed (neither Master nor Xena & Wallaby, version Viktoria & below are not for Stream OS); b) Virtual machine with CentOS 8 Stream installed with packstack - installation was clearly successful (!), quite easy for install (according to official RDO project and its homepage), however there is the real problem with virtual and actual networking: no external network is accessible, router created was OK with external connection (router IP was detected successfully from outside) but no connection was possible from and to instance. So I conclude the Openstack package is not completely documented to resolve problems, however its installation can be quite easy (when successfully finish ;) )
Addition: Of coarse, there are resources with an information how network can be configured, official Openstack docs describes different network configurations as well (however it is difficult to find it for one click and being newbie), but anyway this system requires a lot of time to study before usage.

I am unable to vagrant up

I am using a file from GitHub
It has a vagrant file with it. When I run vagrant up command in my terminal, I get an error.
The terminal should show READ ABOVE message when successful download
I want to type in the address to the site on my browser to start a local development server.
Its pretty old file and the repo was using puphpet but this project seems dead for 2 years, the website is down.
In your case, vagrant is trying to download the box from internet but the owner of this box hosted it under the puphpet domain not available anymore
I am not sure what's the best way to help now:
find another more recent example and start from there
if you want to fix this, you will need https://github.com/LearnWebCode/vagrant-lamp/blob/master/puphpet/config.yaml#L6 and use a different box available on vagrant site, ubuntu 16.04 is pretty old now but you can search one from vagrant box

Cant connect to workspace

Im trying to complete the very first training module offered by MS. Something Im missing that isn't detailed on the documentation of the training.
These are the instructions I'm following
https://github.com/MicrosoftDocs/mslearn-aml-labs/blob/master/labdocs/Lab01.md
All good until I have to run the second command defined on the notebook called
"01-Getting_Started_with_Azure_ML.ipynb".
And yes I entered the device login code as the instructions indicate.
Look at the attached screenshot of the error returned after running the command of the notebook.
Opened a case with Microsoft. They noticed is an issue affecting their VM servers.
This is their reply:
Hi Marbin,
Hope you are doing good. I had discussed this with our team as well. This was a known issue with workspace names with capital letters. So, the workspace name ‘ML_Battlefield’ was creating the issue. This is fixed in SDK version 1.3.0.
In the compute instance notebook, we can update the SDK version to: pip install --upgrade azureml-sdke

Cloudera-manager 4.7

Has anyone else had trouble with the new release of Cloudera manager? '4.7' With brand clean ubuntu vm nodes it seems to be placing a file in /etc/apt/sources.list.d called cloudera-manager.list with "http://archive.cloudera.com/cm4/ubuntu/precise/amd64/cm/ precise-cm4.7.0-SNAPSHOT contrib pointed" to as the source, however this url does not exist and when ever it tries to install my nodes if fails.
Does anyone know where this url is kept on the manager so I could change it before it sends it to my nodes?
Greg,
The repository URL is constructed based on the version of the CM server that you are running. So if the server is reporting itself as "4.7.0-SNAPSHOT", then that's what the node installer will use. Now, we've not published any release that describes itself as 4.7.0-SNAPSHOT, so I'm left scratching my head as to how you got into this situation. If you still have that installation, I would recommend that you:
1) Check the reported version of the server from the Support menu at the top right.
2) Check the full package version(s) as reported by "dpkg -l | grep cloudera"
so that we can establish where the build came from.
Thanks.
PS: The installer url you reference in your update is the latest installer and not a 4.6 installer. It's the one people should use for sure.
