Review request for Ambari and Nate Cole.
Bugs: AMBARI-21866
https://issues.apache.org/jira/browse/AMBARI-21866
Repository: ambari
Description
-------
When running Tez jobs, it was noticed that after killing the applications, ATS
would never move them from the active directory to the done directory. The YARN
folks deep some technical investigation and determined that the reason for this
was a combination of ATS 1.0 and 1.5 configurations co-existing after upgrading
from BigInsights to HDP.
The upgrade auto-merge should have taken care of this for us, but it seems that
1 property was missing from the default stack BI 4.2 (even though it gets added
on install through the UI).
{code}
grep -r --include "*.xml" "yarn.timeline-service.store-class"
src/main/resources/stacks/BigInsights
src/main/resources/stacks/BigInsights/4.0/services/YARN/configuration/yarn-site.xml:
<name>yarn.timeline-service.store-class</name>
src/main/resources/stacks/BigInsights/4.2.5/services/YARN/configuration/yarn-site.xml:
<name>yarn.timeline-service.store-class</name>
{code}
BI 4.2.0 doesn't have this property, which causes the merge to fail. It doesn't
inherit it from BI 4.0 either.
