> 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.
