Assignee: Kihwal Lee
> Newly added NN storage directory won't get initialized and cause space
> exhaustion
> ---------------------------------------------------------------------------------
>
> Key: HDFS-11714
> URL: https://issues.apache.org/jira/browse/HDFS-11714
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.7.3
> Reporter: Kihwal Lee
> Assignee: Kihwal Lee
> Priority: Critical
> Attachments: HDFS-11714.trunk.patch
>
>
> When an empty namenode storage directory is detected on normal NN startup, it
> may not be fully initialized. The new directory is still part of "in-service"
> NNStrage and when a checkpoint image is uploaded, a copy will also be written
> there. However, the retention manager won't be able to purge old files since
> it is lacking a VERSION file. This causes fsimages to pile up in the
> directory. With a big name space, the disk will be filled in the order of
> days or weeks.
