    Description

      Recently we encountered a case where deletion of HDFS snapshots crashed the client that is currently writing to a file under the same snap root. This open file was previously captured in the snapshot using the immutable open file in snapshot feature "dfs.namenode.snapshot.capture.openfiles".
