> Project: Hadoop HDFS

> Reporter: Takuya Fukudome

>
>
> In our cluster, edits has became huge(about 50GB) accidentally and our
> Jounalnodes' disks were busy, therefore {{purgeLogsOlderThan}} took more than
> 30secs. If {{IPCLoggerChannel#purgeLogsOlderThan}} takes too much time,
> Namenode couldn't send other RPC calls to Journalnodes because
> {{o.a.h.hdfs.qjournal.client.IPCLoggerChannel}}'s executor is single thread.
> It will cause namenode shutting down.
> I think IPCLoggerChannel#purgeLogsOlderThan should not block other RPC calls
> like sendEdits.
