Shashikant Banerjee created HDFS-15313:
------------------------------------------

             Summary: Ensure inodes in active filesytem are not deleted during snapshot delete
                 Key: HDFS-15313
                 URL: https://issues.apache.org/jira/browse/HDFS-15313
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: snapshots
            Reporter: Shashikant Banerjee
            Assignee: Shashikant Banerjee
             Fix For: 3.4.0


After HDFS-13101, it was observed that delete snapshot end up cleaning up inodes from active fs which can be referred from only one snapshot as the isLastReference() introduced in HDFS-13101 returns true. The aim of this Jira to add a check to ensure if the Inodes are being referred in the active fs , should not get deleted while deletion of snapshot happens.
