[jira] [Resolved] (HDFS-3237) DatanodeInfo should have a DatanodeID rather than extend it

     [ https://issues.apache.org/jira/browse/HDFS-3237?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eli Collins resolved HDFS-3237.
-------------------------------

    Resolution: Won't Fix

We rely on the current structure - DatanodeDescriptor extends DataNodeInfo extends DatanodeID - in a lot of places. This requires more surgery than is probably worthwhile.

> DatanodeInfo currently extends DatanodeID, the code would be more clear if it had a DatanodeID member instead, as DatanodeInfo is private within the server side and DatanodeID is passed to clients.
