----------------------------------------

+1
May be open another issue to discuss whether we should have Compacting MS for 
META regions at all or not (?)

> Comparators passed to the Memstore's flattened segments seems to be wrong

> While doing HBASE-18945 found that the comparators passed to the 
> CellChunkImmutableSegment and CellArrayImmutableSegment are sometimes wrong. 
> We pass the comparator that we got from the Store but when doing 
> reinitializeCellSet we always use CellComparator.COMPARATOR.
> From code I don think we are stopping the META region to also go through 
> CompactingMemstore. If we do that then this JIRA is invalid. But considering 
> that is not the case we should fix it and pass the right comparator.
