Owen O'Malley commented on HDFS-3466:
-------------------------------------
It is good to allow the keytabs that need to be shared between services, such
as spnego to be shared. At this point we can't change the name without a very
good reason, since it will break compatibility with hadoop-1.0.X. We also need
to fix the secondary namenode with exactly the same problem.
> 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
> the keytab. It should use the DFS_WEB_AUTHENTICATION_KERBEROS_KEYTAB_KEY to
> do it.
