> Under compaction mark may leak
> ------------------------------
>
> Key: HBASE-27152
> URL: https://issues.apache.org/jira/browse/HBASE-27152
> Project: HBase
> Issue Type: Bug
> Components: Compaction
> Affects Versions: 3.0.0-alpha-2, 2.4.12
> Reporter: Xiaolin Ha
> Assignee: Xiaolin Ha
> Priority: Major
> Fix For: 2.5.0, 3.0.0-alpha-4
>
>
> 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.
