      Description

      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.
