Gour Saha created YARN-2823:
-------------------------------
Summary: NullPointerException in RM HA enabled 3-node cluster
Key: YARN-2823
URL: https://issues.apache.org/jira/browse/YARN-2823
Project: Hadoop YARN
Issue Type: Bug
Reporter: Gour Saha
Branch:
2.6.0
Environment:
A 3-node cluster with RM HA enabled. The HA setup went pretty smooth (used
Ambari) and then installed HBase using Slider. After some time the RMs went
down and would not come back up anymore. Following is the NPE we see in both
the RM logs.
