Ted Yu commented on HBASE-8299:
-------------------------------
NoStuckSmallestPolicy needs license header.
For NoStuckSmallestPolicy#applyCompactionPolicy():
{code}
+ if (bestSelection.size() == 0 && mightBeStuck) {
+ return new ArrayList<StoreFile>(smallest);
+ }
{code}
When bestSelection.size() == 0 && !mightBeStuck, we return bestSelection. Would
smallest be empty in this case ?
> ExploringCompactionPolicy can get stuck in rare cases.
