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

Haohui Mai commented on HDFS-5796:
----------------------------------

bq. Forgive me if I am wrong, but I see that the the request actually goes thru multiple Filters
before it gets to WebHDFS

It can be done through specifying custom filters, just like what needs to be done to enable
SPNEGO for the web UI today. It requires some configuration but it can be done. The mechanisms
of filters are overdue for some redesigns.

> 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.
