Summary: Disable in-memory flush when eplaying from WAL
Key: HBASE-17662
URL: https://issues.apache.org/jira/browse/HBASE-17662
Project: HBase
Issue Type: Sub-task
Reporter: Anastasia Braginsky
When replaying the edits from WAL, the region's updateLock is not taken,
because a single threaded action is assumed. However, the thread-safeness of
the in-memory flush of CompactingMemStore is based on taking the region's
updateLock.
The in-memory flush can be skipped in the replay time (anyway everything is
flushed to disk just after the replay). Therefore it is acceptable to just skip
the in-memory flush action while the updates come as part of replay from WAL.
