> During HA upgrade, JournalNode should create a new committedTxnId file in the

> Key: HDFS-7131
> URL: https://issues.apache.org/jira/browse/HDFS-7131
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: qjm
> Affects Versions: 2.4.0
> Reporter: Jing Zhao
> Assignee: Jing Zhao
> Attachments: HDFS-7131.000.patch, HDFS-7131.001.patch
>
>
> Currently while doing HA upgrade, we do not create a new committedTxnId file
> in the new current directory of JournalNode. And before we have the fix in
> HDFS-7042, since the file channel is never closed, for any new journal we're
> actually updating the committedTxnId file in the previous directory. This can
> cause NN to fail to start while rollback.
> HDFS-7042 fixes the main part of the issue: the file channel inside of the
> committedTxnId object gets closed thus later a new file can be created in the
> current directory. But maybe it is still better to copy the content file
> during the upgrade so that we can always use it for sanity check.
