> High read/write intensive regions may cause long crash recovery

> Key: HBASE-22072
> URL: https://issues.apache.org/jira/browse/HBASE-22072
> Project: HBase
> Issue Type: Bug
> Components: Performance, Recovery
> Affects Versions: 2.1.2
> Reporter: Pavel
> Assignee: ramkrishna.s.vasudevan
> Priority: Major
> Attachments: HBASE-22072.HBASE-21879-v1.patch

>
> Compaction of high read loaded region may leave compacted files undeleted
> because of existing scan references:
> INFO org.apache.hadoop.hbase.regionserver.HStore - Can't archive compacted
> file hdfs://hdfs-ha/hbase... because of either isCompactedAway=true or file
> has reference, isReferencedInReads=true, refCount=1, skipping for now
> If region is either high write loaded this happens quite often and region may
> have few storefiles and tons of undeleted compacted hdfs files.
> Region keeps all that files (in my case thousands) untill graceful region
> closing procedure, which ignores existing references and drop obsolete files.
> It works fine unless consuming some extra hdfs space, but only in case of
> normal region closing. If region server crashes than new region server,
> responsible for that overfiling region, reads hdfs folder and try to deal
> with all undeleted files, producing tons of storefiles, compaction tasks and
> consuming abnormal amount of memory, wich may lead to OutOfMemory Exception
> and further region servers crash. This stops writing to region because number
> of storefiles reach *hbase.hstore.blockingStoreFiles* limit, forces high GC
> duty and may take hours to compact all files into working set of files.
> Workaround is a periodically check hdfs folders files count and force region
> assign for ones with too many files.
> It could be nice if regionserver had a setting similar to
> hbase.hstore.blockingStoreFiles and invoke attempt to drop undeleted
> compacted files if number of files reaches this setting.
