Subject Re: Java Null Pointer for Unmanaged AM
Date Thu, 28 Apr 2016 15:25:41 GMT

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.

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

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

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.
