Subject [jira] [Commented] (HDFS-4900) Print user when services are started
Date Thu, 13 Jun 2013 17:55:21 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4900?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13682474#comment-13682474
] 

Brandon Li commented on HDFS-4900:
----------------------------------

Looks like Namenode does prints both owner's name and group.

Datanode (JournalNode) and Secondarynamenode don't start FSNamesystem, and thus don't print
the users name/group.

> Printing user name during start can help debug access permission related issues, e.g.,
the namenode storage directory is not accessible by the user who starts the service.
