Subject [jira] [Created] (HBASE-16964) Successfully archived files are not cleared from compacted store file list if archiving of any file fails
Date Fri, 28 Oct 2016 22:54:58 GMT

-------------------------------------

             Summary: Successfully archived files are not cleared from compacted store file
list if archiving of any file fails
                 Key: HBASE-16964
                 URL: https://issues.apache.org/jira/browse/HBASE-16964
             Project: HBase
          Issue Type: Bug
          Components: regionserver
            Reporter: Gary Helmling
            Assignee: Gary Helmling
            Priority: Blocker
             Fix For: 1.3.0


In HStore.removeCompactedFiles(), we only clear archived files from StoreFileManager's list
of compactedfiles if _all_ files were archived successfully.  If we encounter an error archiving
any of the files, then any files which were already archived will remain in the list of compactedfiles.

Even worse, this means that all subsequent attempts to archive the list of compacted files
will fail (as the previously successfully archived files still in the list will now throw
FileNotFoundException), and the list of compactedfiles will never be cleared from that point
on.

Finally, when the region closes, we will again throw an exception out of HStore.removeCompactedFiles(),
in this case causing a regionserver abort.
