huaxiang sun commented on HBASE-16578:

Thanks [~jingcheng.du@intel.com]! I am still digesting the info and will probably come back
tomorrow. I have another testing case which is not reliably giving failure (the first case)
to verify.

> I have a unittest case, which could explore the mob data loss issue. The root cause is
that with the following line:
> https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/mob/compactions/PartitionedMobCompactor.java#L625
> It will make the old mob reference cell win during compaction.
