> Key: HDFS-6601
> URL: https://issues.apache.org/jira/browse/HDFS-6601
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.5.0
> Reporter: Kihwal Lee
> Assignee: Kihwal Lee
> Priority: Blocker
> Fix For: 3.0.0, 2.5.0
>
> Attachments: HDFS-6601.patch

>
> After HDFS-6545, we have noticed a couple of issues.
> - The storage dir's VERSION file is not properly updated. This becomes a
> problem when there is a layout version change. We can have the finalization
> do {{storage.writeAll()}}
> - {{OP_ROLLING_UPGRADE_FINALIZE}} cannot be replayed, once the corresponding
> {{OP_ROLLING_UPGRADE_START}} is consumed and a new fsimage is created (e.g.
> rollback image). On restart, NN terminates complaining it can't finalize
> something that it didn't start. We can make NN ignore
> {{OP_ROLLING_UPGRADE_FINALIZE}} if no rolling upgrade is in progress.
