> HBASE-26249 introduced an under compaction mark to reduce repeatedly compactions for the same stores for a short period of time after bulk loading files.
> Since the mark adding and removing are in difference threads,
> {code:java}
> pool.execute(
>   new CompactionRunner(store, region, compaction, tracker, completeTracker, pool, user));
> if (LOG.isDebugEnabled()) {
>   LOG.debug(
>     "Add compact mark for store {}, priority={}, current under compaction "
>       + "store size is {}",
>     getStoreNameForUnderCompaction(store), priority, underCompactionStores.size());
> }
> underCompactionStores.add(getStoreNameForUnderCompaction(store)); {code}
>  it happens that the concurrently of thread-1 using underCompactionStores.add() and thread-2 which running a CompactionRunner that using underCompactionStores.remove(). If the removing happens before adding, the mark will leak.
