    Description

      When DataNode fails to add a volume, it adds one failure message to errorMessageBuilder in DataNode#refreshVolumes. However, the detailed error messages are not logged in DataNode's log and they are emitted from clients.

      This JIRA makes DataNode reports detailed failure in its log.
