[Sunil G]

Hi Eric,

Thanks for helping in verifying the release.

Post YARN-7370, preemption configs are refreshable. I tried to test by
making some changes in capacity-scheduler.xml and invoking yarn rmadmin
-refreshQueues.
I can see the changes reflected as per logs after refresh. Could you please
help to give some more scenarios so that i can try to reproduce.
Meanwhile i ll try some other combinations as well and let you know.

Re: [VOTE] Release Apache Hadoop 3.2.0 - RC0

[Eric Payne]

Sunil,

So, the basic symptoms are that if preemption is enabled on any queue, the 
preemption is disabled after a 'yarn rm -refreshQueues'. In addition, all of 
the preemption-specific properties are set back to the default values.

This was introduced in branch-3.1, so it is NOT new behavior for release 3.2.0. 
I am still tracking down the cause. I will open a JIRA once I do further 
investigation if there is not one already.

This will be a problem for installations which use preemption and which use the 
refreshQueues feature.

Thanks,
-Eric

Sunil, thanks for all of the hard work on this release.

I have discovered that queue refresh doesn't work in some cases. For example, 
when I change yarn.scheduler.capacity.root.default.disable_preemption, it

I am still investigating, but I thought I should bring this up asap.

 so this patch removes the "out.writeBytes("\n");". As the encoder is buffered, 
this can cause JSON errors in the output stream by directly writing to it.

Sunil, thanks for all of the hard work on this release.

I have discovered that queue refresh doesn't work in some cases. For example, 
when I change yarn.scheduler.capacity.root.default.disable_preemption, it 
doesn't take effect unless I restart the RM.

I am still investigating, but I thought I should bring this up asap.
