Clara Xiong commented on HBASE-15454:
-------------------------------------
For major compaction, we have a laundry list of checks which is in
shouldPerformMajorCompaction to determine whether we should do major compaction
at a CompactionChecker run. You probably want that too for this special
compaction. And in SortedCompactionPolicy.selectCompaction, we spend the effort
to determin whether we can actually do major compaction: fileCompacting,
reference, file count < max file allowed. Please have the logic there than
passing in candidate files.
Or if you believe this compaction is mutually exclusive/interchangeable with
major compaction. which IS as I understand from my interpretation, you can even
make it interchangeable with major compaction with a config switch so you use
use/extend the logic for triggering.

> redundancy.
