> Fix OzoneContainer start method
> -------------------------------
>
> Key: HDDS-1475
> URL: https://issues.apache.org/jira/browse/HDDS-1475
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Components: Ozone Datanode
> Reporter: Bharat Viswanadham
> Assignee: Aravindan Vijayan
> Priority: Major
> Labels: newbie, pull-request-available
> Fix For: 0.5.0
>
> Time Spent: 3h 10m
> Remaining Estimate: 0h
>
> In OzoneContainer start() we have
> {code:java}
> startContainerScrub();
> writeChannel.start();
> readChannel.start();
> hddsDispatcher.init();
> hddsDispatcher.setScmId(scmId);{code}
>
> Suppose here if readChannel.start() failed due to some reason, from
> VersionEndPointTask, we try to start OzoneContainer again. This can cause an
> issue for writeChannel.start() if it is already started.
>
> Fix the logic such a way that if service is started, don't attempt to start
> the service again. Similar changes needed to be done for stop().
