> Unmonitored HBase service could accumulate Status objects and OOM
> -----------------------------------------------------------------
>
> Key: HBASE-10046
> URL: https://issues.apache.org/jira/browse/HBASE-10046
> Project: HBase
> Issue Type: Bug
> Components: monitoring
> Affects Versions: 0.96.0, 0.94.14
> Reporter: Aditya Kishore
> Assignee: Aditya Kishore
> Attachments: HBASE-10046.patch, HBASE-10046_0.94.patch
>
>
> This was observed in a cluster where HBase Master UI was not monitored for
> quite a while. During this period, a distributed log spitting task failed in
> an in-completable way and Master kept recreating the task over and over again.
> And each such task would create a monitored status...
> {code:title=SplitLogManager.java}
> .......
> public long splitLogDistributed(final List<Path> logDirs, PathFilter
> filter)
> throws IOException {
> MonitoredTask status = TaskMonitor.get().createStatus(
> "Doing distributed log split in " + logDirs);
> .......
> {code}
> ...which kept accumulating on heap.
> Now these monitored tasks get cleaned only when someone looks at the service
> UI otherwise they keep growing boundless.
> The postmortem of the heap dump showed that these task object occupied 99% of
> HBase master heap accumulated over a week.
