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

bq. This ticket has stalled again, blocking the 2.7 release.

Sort of.  Everyone here went to HADOOP-10703 with the hope that it would fix the problem.  However, it did not.

> 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.
