> Key: HDFS-7120
> URL: https://issues.apache.org/jira/browse/HDFS-7120
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: journal-node, namenode
> Reporter: Chris Nauroth
> Assignee: Chris Nauroth
> Priority: Major
>
> If the NameNode or JournalNode aborts due to an unexpected error in the
> metadata directories, often the root cause is that the metadata files are in
> an unexpected state, or permissions are broken on the directories. This
> issue proposes that during abort, we write additional information about the
> directory state and permissions to the logs. This can help speed up
> diagnosis, and ultimately recovery.
