Rahul Singhal updated HDFS-6340:
--------------------------------
Attachment: HDFS-6340.patch
Rebased to branch 'trunk' with Kihwal's suggestions.
Sorry for the delay but I was trying to wrap my head around the
{{nn.isStandbyState()}} issue. [~kihwal], can you please file new issue? (I
feel you would do more justice to its description)
> DN can't finalize upgarde
> -------------------------

> Key: HDFS-6340
> URL: https://issues.apache.org/jira/browse/HDFS-6340
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode
> Affects Versions: 2.4.0
> Reporter: Rahul Singhal
> Priority: Blocker
> Attachments: HDFS-6340-branch-2.4.0.patch, HDFS-6340.patch

> I upgraded a (NN) HA cluster from 2.2.0 to 2.4.0. After I issued the
> '-finalizeUpgarde' command, NN was able to finalize the upgrade but DN
> couldn't (I waited for the next block report).
> I think I have found the problem to be due to HDFS-5153. I will attach a
> proposed fix.
