huaxiang sun commented on HBASE-15261:
--------------------------------------

The exception is same as
http://stackoverflow.com/questions/34905296/hbase-periodicmemstoreflusher-exception

There is no logs so it is hard to tell the root cause.

t is set in these threads and it is checked in the calling thread. Need to make it volatile
so the checking will not miss any exceptions from opening daughter regions.
