> 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() check for the parent dir introduced in HDFS-13101 may
> return true in certain cases. 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.
