Elliott Clark commented on HBASE-8299:
--------------------------------------

I don't understand what you're looking for.  You're asking to change the whole 
algorithm without specific requests.  If you want to propose another algorithm 
for compaction selection then another issue would be best.

As it stands now ExploringCompactionPolicy is broken and either needs to be 
changed so that it can't get stuck (done in this patch) or 
ExploringCompactionPolicy needs to be removed (breaking bulk loads again).
                
> ExploringCompactionPolicy can get stuck in rare cases.
