Allen Wittenauer commented on HDFS-5796:
----------------------------------------
Hmm. I'm actually not certain we can use the SignerSecretProvider without
breaking backward compatibility since it uses a different configuration
property. :(
This is just a mess. :(
> The file system browser in the namenode UI requires SPNEGO.

> 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.
