Rohith Sharma K S commented on YARN-7032:
-----------------------------------------
I found that when HBase is enabled with authorization by configuring
_hbase.coprocessor.region.classes_ with value
_org.apache.hadoop.hbase.security.access.AccessController,_ makes RegionServer
to go down along FlowRunCoprocessor. This is because when authorization is
enabled, additional attributes are added to put#attributes map by
AccessController. So FlowRunCoprocessor should handle null values before adding
into tags

> It is seen randomly that hbase co-processor fails to start with NPE. But
> again starting RegionServer, able to succeed in starting RS.
