Aaron T. Myers commented on HDFS-3466:
--------------------------------------
It's fine by me to support folks who already have a keytab which contains only
the HTTP principal, I just want to make sure we continue to support folks who
are used to putting entries for both principals in the same keytab. So, let's
make this code first check the config for
DFS_WEB_AUTHENTICATION_KERBEROS_KEYTAB_KEY, and then fall back to using
DFS_NAMENODE_KEYTAB_FILE_KEY if that's not set.
> The SPNEGO filter for the NameNode should come out of the web keytab file

> Currently, the spnego filter uses the DFS_NAMENODE_KEYTAB_FILE_KEY to find
