Background on ats-hbase start success:: We had setStoragePolicy exception on OneFS for yarn-ats hbase region server and below messages respectively on HDP and OneFS cluster.

As a resolution, we set below 2 properties in custom hbase-site.xml file and setstoragePolicy exception got resolved.

 Custom yarn-hbase-site.xml

'hbase.wal.storage.policy' to ‘NONE’

‘hbase.hstore.block.storage.policy’ to ‘NONE’

 

 

*********

NOW, we have a new issue that is OneFS HDFS log and /var/log/hadoop-yarn/embedded-yarn-ats-hbase/hbase-yarn-ats-regionserver-***.log gets flooded with below error messages.*OneFS HDFS Log

On checking the ats-hbase app logs, found hbase region server is trying to flush the old edits to free the WAL and it fails due to authentication issue. 

Why yarn-ats hbase expects OneFS(namenode and datanode) to have a yarn principle?
