Subject Re: Java Null Pointer for Unmanaged AM

What version of hadoop or distribution are you using? I believe the issue was logged in YARN
4452 and fixed in certain versions, including HDP 2.4.
https://issues.apache.org/jira/browse/YARN-4452

If you use the newer versions of hadoop, you should not see the issue.
Thanks
Vineet

Hi Guys,

I am seeing errors in YARN Resource Manager for Null pointer
exceptions. The error is encountered for Unmanaged AM for HAWQ.
However, when I disable the yarn parameter for
yarn.resourcemanager.system-metrics-publisher.enabled everything works
fine.

I see there was another email thread for this issue back in Dec 2015.
The thread was exchanged under the subject line:

Meet A java null pointer when use unmanaged AM and
yarn.resourcemanager.system-metrics-publisher.enabled is enable

I am not sure if this has been fixed or if there is any jira available
on this issue.

I'd appreciate the right direction on this problem.
