Elliott Clark commented on HBASE-8299:
--------------------------------------
bq.If something calls selection non-stop when there's no reasonable selection
to be made it's a different problem.
Exactly that's the odd thing not the normal. We shouldn't change the algorithm
to protect a user from that. We should make sure the normal case is fine. The
normal case is that compaction is needed because store says needsCompaction() =
true. If there's some times that compactions are requested when not needed
then we should fix that not patch around it here.
> ExploringCompactionPolicy can get stuck in rare cases.
