Components: regionserver
Affects Versions: 0.96.0
Reporter: Jerry He
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:
