Vinod Kumar Vavilapalli commented on HDFS-5796:
-----------------------------------------------

This ticket has stalled again, blocking the 2.7 release.

[~wheat9], despite your summary, I don't follow the TODO items. Can you help summarize what
needs to be done to unblock 2.7?

> 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.
