 Problem
hbase oldWALs cleanup not working

Environment/Conditions/Configuration
HDP 2.1

Cause
This could be due to the old logs wal cleaner thread not running within HBase Master JVM. You will see the following message being printed in Hbase master logs

2018-02-22 03:37:52,116 WARN [master:masterhost:60000.oldLogCleaner] cleaner.CleanerChore: A file cleanermaster:masterhost:60000.oldLogCleaner is stopped, won't delete any more files in:hdfs://NNID/apps/hbase/data/oldWAL

Solution
Hbase master services need to be restarted to resume OldLogCleaner thread. Once restarted, it will resolve the space issue by cleaning up the accumulated old WAL files.

Special Considerations
