> This Jira is to remove the datanodeID file. After ContainerIO work (HDDS-48
> branch) is merged, we have a version file in each Volume which stores
> datanodeUuid and some additional fields in that file.
> And also if this disk containing datanodeId path is removed, that DN will now
> be unusable with current code.
