Description

Saw the following in region server log repeatedly:

2016-09-26 10:13:33,219 WARN org.apache.hadoop.hbase.regionserver.HRegion: Failed getting lock in batch put, row=1
java.io.IOException: Timed out waiting for lock for row: 1

Region name was not logged - making troubleshooting a bit difficult.
