Anoop Sam John commented on HBASE-18992:
----------------------------------------
I was also thinking that we dont make in memory compaction for the META
regions. Ya at first search I can not see we doing this. Then it is a bug.
But may be we should make META region not to use in memory compaction? Any way
it is better to correct this bug.
> Comparators passed to the Memstore's flattened segments seems to be wrong

> Key: HBASE-18992
> URL: https://issues.apache.org/jira/browse/HBASE-18992
> Project: HBase
> Issue Type: Bug
> Affects Versions: 2.0.0-alpha-3
> Reporter: ramkrishna.s.vasudevan
> Assignee: ramkrishna.s.vasudevan
> Fix For: 2.0.0-beta-1
>
>
> 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.
