Assignee: Hemant Kumar
> Tarball creation interfering with snapshot purge
> -------------------------------------------------
>
> Key: HDDS-12210
> URL: https://issues.apache.org/jira/browse/HDDS-12210
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Hemant Kumar
> Assignee: Hemant Kumar
> Priority: Major
>
> If tarball creation is in the process while the snapshot is getting purged,
> it fails the snapshot db dir delete command. Because of that snapshot db dir
> lingers around even tho snapshot is purged form the snapshotInfoTable and
> needs manual intervention to delete the dir.
