stack commented on HBASE-938:
-----------------------------
Patch seems to be working but it introduces a new issue in that it ensures that
we check for major compaction every 24 hours and that a major compation will
run every 24 hours, even if no flushes have come through meantime. We don't
want all hbase data rewritten every 24 hours.
Will try and fix as part of this issue.

> due.
