Getting user not found issue when starting spark job

New Contributor

Facing a problem where randomly we will get "User not found" error when trying to start a container in checking namenode logs I can see the following:

Re: Getting user not found issue when starting spark job

Hi @paleerbccm 

The issue here is that this user ID doesn't exist on one of your YARN NodeManager machines. That probably also explains the randomness of the issue. So long as a container doesn't end up allocated on that machine then you won't run into any problems.

You need to find where the containers fail to launch with that exception, then SSH into the host machine and confirm the problem by running:

 

id pyqy0srv0z50

You will then need to be sure to create this user on that machine and make sure that the user's group membership matches whatever you have on all your other hosts.

This is still happening for us see the error in our production yarn logs below.
 
The issue happened again today.
 
AM Container for appattempt_1573918482316_0389_000001 exited with exitCode: -1000
For more detailed output, check the application tracking page: http://guerlpahdp001.fg.rbc.com:8088/cluster/app/application_1573918482316_0389 Then click on links to logs of each attempt.

Re: Getting user not found issue when starting spark job

@paleerbccm it's still the same issue but the log you're sharing doesn't show the details we would need. Your problem is that when the container for the ApplicationMaster attempts to launch on a particular host machine as the ptzs0srv0z50, this shell command fails because the user ID doesn't exist on this machine.

What you need to do is identify where the Application Master attempted to run. You can do this from the Resource Manager's WebUI. Please refer to the following screenshot for example and note the highlighted red box:

Screen Shot 2019-11-20 at 2.36.26 PM.png

You'll see in this example that the first ApplicationMaster attempt was on the host machine worker.example.com. You would then need to SSH into that host machine and run the following command to see if this user actually exists or not:

id ptzs0srv0z50

I have run the id command for the user on both nodes.

 

Both show the user is valid.

Re: Getting user not found issue when starting spark job

This issue would really require further debugging. For whatever reason, at that particular time something happened with the user ID resolution. We've seen customers before that had similar issues when tools like SSSD is being used:
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/html/deployment_guide/sssd-...

One idea here is to create a shell script that runs the command 'id ptz0srv0z50' and 'id -Gn ptz0srv0z50' in a loop based on some interval. say 10, 20 or 30 seconds and when the problem occurs just go over the output of that shell script and see if you notice anything different in the output at the time of the issue.
