Subject: Re: [VOTE]: Hadoop Ozone 0.4.0-alpha RC0 release

Thanks Ajay for working on release.

We've found an issue in DN where the root filesystem is getting filled after running the cluster
for a while. This is because after importing a container successfully, datanode is not deleting
the container tar.gz file from working directory(/tmp by default).

More details in https://issues.apache.org/jira/browse/HDDS-1417
