stack commented on HBASE-938:
-----------------------------
I will up the period, make it two days at least.
But was thinking too that we should mark files that have been major compacted
-- write the fact into the files metadata or into the file name -- and before
running another, check the column descriptor to see if TTL is forever; if it
is, do not run another major compaction if only one file to compact.
> major compaction period is not checked periodically
