> Race in compacted file deletion between HStore close() and
> closeAndArchiveCompactedFiles()
> ------------------------------------------------------------------------------------------
>
> Key: HBASE-16788
> URL: https://issues.apache.org/jira/browse/HBASE-16788
> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 1.3.0
> Reporter: Gary Helmling
> Assignee: Gary Helmling
> Priority: Blocker
> Attachments: 16788-suggest.v2, HBASE-16788.001.patch,
> HBASE-16788.002.patch, HBASE-16788_1.patch
>
>
> HBASE-13082 changed the way that compacted files are archived from being done
> inline on compaction completion to an async cleanup by the
> CompactedHFilesDischarger chore. It looks like the changes to HStore to
> support this introduced a race condition in the compacted HFile archiving.
> In the following sequence, we can wind up with two separate threads trying to
> archive the same HFiles, causing a regionserver abort:
> # compaction completes normally and the compacted files are added to
> {{compactedfiles}} in HStore's DefaultStoreFileManager
> # *threadA*: CompactedHFilesDischargeHandler runs in a RS executor service,
> calling closeAndArchiveCompactedFiles()
> ## obtains HStore readlock
> ## gets a copy of compactedfiles
> ## releases readlock
> # *threadB*: calls HStore.close() as part of region close
> ## obtains HStore writelock
> ## calls DefaultStoreFileManager.clearCompactedfiles(), getting a copy of
> same compactedfiles
> # *threadA*: calls HStore.removeCompactedfiles(compactedfiles)
> ## archives files in {compactedfiles} in HRegionFileSystem.removeStoreFiles()
> ## call HStore.clearCompactedFiles()
> ## waits on write lock
> # *threadB*: continues with close()
> ## calls removeCompactedfiles(compactedfiles)
> ## calls HRegionFIleSystem.removeStoreFiles() ->
> HFileArchiver.archiveStoreFiles()
> ## receives FileNotFoundException because the files have already been
> archived by threadA
> ## throws IOException
> # RS aborts
> I think the combination of fetching the compactedfiles list and removing the
> files needs to be covered by locking. Options I see are:
> * Modify HStore.closeAndArchiveCompactedFiles(): use writelock instead of
> readlock and move the call to removeCompactedfiles() inside the lock. This
> means the read operations will be blocked while the files are being archived,
> which is bad.
> * Synchronize closeAndArchiveCompactedFiles() and modify close() to call it
> instead of calling removeCompactedfiles() directly
> * Add a separate lock for compacted files removal and use in
> closeAndArchiveCompactedFiles() and close()
