-------------------------------------
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.
