Jean-Daniel Cryans commented on HBASE-1058:
-------------------------------------------
No problem.
What I mean is that we should jump start that thread to a defined value. For
example:
1. While flushing, we see that we have > than 4 stores files so we ask for a
compaction and wait for it. The compaction of 4 files took 2 minutes.
2. While flushing, we see that we have > than 4 stores files so we start the
CompactionLimitThread and set it to start on cell 5 of the limitSteps array. We
then ask for a compaction and wait for it. The compaction of 2 files took less
than 2 minutes.
Currently we are at 1, I think of something like 2.
