Anoop Sam John commented on HBASE-18992:
----------------------------------------
bq.The interesting thing is why no failure is caused by this issue? The meta
data is too small to trigger any in-memory compaction?
Ya may be.
In another issue we can change it NOT to do in memory compaction for the META
region?
> 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.
