Subject [jira] [Commented] (HDFS-5796) The file system browser in the namenode UI requires SPNEGO.

Allen Wittenauer commented on HDFS-5796:
----------------------------------------

Can we split out some of the debug and logging changes into a separate patch so we can get
those committed while y'all are still discussing the merits of the approach?  Those are useful
no matter what kind of auth you are doing... :D

> After HDFS-5382, the browser makes webhdfs REST calls directly, requiring SPNEGO to work
between user's browser and namenode.  This won't work if the cluster's security infrastructure
is isolated from the regular network.  Moreover, SPNEGO is not supposed to be required for
user-facing web pages.
