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

Arun Suresh commented on HDFS-5796:
-----------------------------------

bq. The irony is that our handler is using the AltKerberos code (which means it does support
SPNEGO)
Hmm.. technically, it does.. you can just configure it to bypass SPNEGO for browser based
access...

> 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.
