Description

I have seen during a stress testing client was getting

"RetriesExhaustedWithDetailsException: Failed 748 actions: NotServingRegionException"

On the master log, 2014-02-08 20:43 is the timestamp from OFFLINE to SPLITTING_NEW, 2014-02-08 21:41 is the timestamp from SPLITTING_NEW to OPEN.

The corresponding time period on the region sever log is:

2014-02-08 20:44:12,662 WARN org.apache.hadoop.hbase.regionserver.HRegionFileSystem: .regioninfo file not found for region: 010c1981882d1a59201af5e2dc589d44

There were no INFO related to these two regions until: (at the end see this: Split took 57mins, 16sec)
