> URL: https://issues.apache.org/jira/browse/HDFS-15313
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: snapshots
> Reporter: Shashikant Banerjee
> Assignee: Shashikant Banerjee
> Priority: Major
> Fix For: 3.4.0
>
> Attachments: HDFS-15313.000.patch, HDFS-15313.001.patch

>
> After HDFS-13101, it was observed in one of our customer deployments that
> delete snapshot ends 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.
