Chris Nauroth updated HDFS-4748:
--------------------------------
Attachment: HDFS-4748.1.patch
This patch changes {{MiniJournalCluster#restartJournalNode}} so that it
remembers the newly created {{JournalNode}} instance. This guarantees that the
node will get stopped later in {{MiniJournalCluster#shutdown}}.
With this patch, I get consistent successful test runs for
{{TestQuorumJournalManager}} on all platforms.
> MiniJournalCluster#restartJournalNode leaks resources, which causes sporadic
> test failures

> {{MiniJournalCluster#restartJournalNode}} stops a {{JournalNode}} and then
> recreates a new one with the same configuration. However, it does not
> maintain a reference to the new {{JournalNode}} instance, so therefore it
> doesn't get stopped inside {{MiniJournalCluster#shutdown}}. The
> {{JournalNode}} holds a file lock on its underlying storage, so this can
> cause sporadic failures in tests like {{TestQuorumJournalManager}}.
