Bharat Viswanadham updated HDDS-1475:
-------------------------------------
Description:
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().
