Ted Yu commented on HBASE-16578:
--------------------------------

I ran the test using master branch:

Running org.apache.hadoop.hbase.mob.compactions.TestMobCompaction
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 20.496 sec - in org.apache.hadoop.hbase.mob.compactions.TestMobCompaction

Is this expected ?

> 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.
