Subject Requested row out of range for row lock while batch put operation
Date Tue, 14 Apr 2015 13:03:34 GMT
Our RegionServers kept getting this exception and were therefore unable to
response to other requests:

org.apache.hadoop.hbase.regionserver.HRegion: Failed getting lock in batch

I guess maybe the batch put operation happened during the table split, Any
other possible causes and how to prevent it from happening again?
