Subject [jira] [Updated] (HBASE-16964) Successfully archived files are not cleared from compacted store file list if archiving of any file fails
Date Wed, 02 Nov 2016 22:46:58 GMT

     [ https://issues.apache.org/jira/browse/HBASE-16964?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Gary Helmling updated HBASE-16964:
----------------------------------
    Attachment: HBASE-16964.003.patch

Adding a null check to the FUNC_FILE_TO_PATH Function to make findbugs happy.

[~ram_krish], [~anoop.hbase], please take a look at the update.

The reported hanging tests all pass for me locally.

> 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.
