> Bug in check for DN re-registration with different storage ID
> -------------------------------------------------------------
>
> Key: HDFS-3224
> URL: https://issues.apache.org/jira/browse/HDFS-3224
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Eli Collins
> Assignee: Jason Lowe
> Priority: Minor
> Attachments: HDFS-3224.patch, HDFS-3224.patch
>
>
> DatanodeManager#registerDatanode checks the host to node map using an IP:port
> key, however the map is keyed on IP, so this check will always fail. It's
> performing the check to determine if a DN with the same IP and storage ID has
> already registered, and if so to remove this DN from the map and indicate
> that eg it's no longer hosting these blocks. This bug has been here forever.
