> Snapshot diff could be corrupted after concat

> Key: HDFS-13120
> URL: https://issues.apache.org/jira/browse/HDFS-13120
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode, snapshots
> Reporter: Xiaoyu Yao
> Assignee: Xiaoyu Yao
> Priority: Major
> Attachments: HDFS-13120.001.patch
>
>
> The snapshot diff can be corrupted after concat files. This could lead to
> Assertion upon DeleteSnapshot and getSnapshotDiff operations later.
> For example, we have seen customers hit stack trace similar to the one below
> but during loading edit entry of DeleteSnapshotOp. After the investigation,
> we found this is a regression caused by HDFS-3689 where the snapshot diff is
> not fully cleaned up after concat.
> I will post the unit test to repro this and fix for it shortly.
