Jonathan Hsieh commented on HBASE-13531:
----------------------------------------
This is a problem with flushes conflicting with the acid guarantees (similar to
the problem one we had way back). In the two acid violation cases we have a
flush procedure running causing the acid in the time frame where the acid
violation occurs.
