>
> Multithreaded compactions (HBASE-1476) will solve the problem of major
> compactions clogging high-priority minor compactions. However, there is
> still a problem here. Since compactions are store-level, the store
> undergoing major compaction will have it's storefile count increase during
> the major. We really need a way to allow multiple outstanding compactions
> per store. compactSelection() should lock/reserve the files being used for
> compaction. This will also allow us to know what we're going to compact when
> inserting into the CompactSplitThread and make more informed priority
> queueing decisions.
