Tsz Wo Nicholas Sze commented on HADOOP-10301:
----------------------------------------------

For client-side NPEs, do you mean HADOOP-9363?  Then, do we also need HADOOP-9363?  There
is no patch in HADOOP-9363.

> The hadoop-auth AuthenticationFilter returns a 401 Unauthorized without a WWW-Authenticate
headers.  The is illegal per the HTTP RPC and causes a NPE in the HttpUrlConnection.
> This is half of a fix that affects webhdfs.  See HDFS-4564.
