-----------------------------------
Summary: 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
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.
