Description

Seems like an old bit of code but its causing warning:

Dodgy code Warnings
Code Warning
DLS Dead store to $L8 in org.apache.hadoop.hbase.regionserver.HRegionServer.initializeMemStoreChunkCreator()
Bug type DLS_DEAD_LOCAL_STORE (click for details)
In class org.apache.hadoop.hbase.regionserver.HRegionServer
In method org.apache.hadoop.hbase.regionserver.HRegionServer.initializeMemStoreChunkCreator()
Local variable stored in JVM register 8
At HRegionServer.java:[line 1593]

This seems to be only thing between 2.1 being a blue run in last few instances. Let me fix.
