Subject [jira] [Commented] (HDFS-1574) HDFS cannot be browsed from web UI while in safe mode
Date Thu, 23 Jun 2011 15:16:27 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1574?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13053916#comment-13053916

Todd Lipcon commented on HDFS-1574:

I think HDFS should be browsable in safe-mode -- perhaps in such a way that we just log a
warning that delegation tokens will be non-persistent.

> As of HDFS-984, the NN does not issue delegation tokens while in safe mode (since it
would require writing to the edit log). But the browsedfscontent servlet relies on getting
a delegation token before redirecting to a random DN to browse the FS. Thus, the "browse the
filesystem" link does not work while the NN is in safe mode.
