Robert Kanter updated OOZIE-2485:
---------------------------------
    Description: 
When using Hadoop 2.4.0 or later, the Oozie client doesn't update the auth 
token when it expires.  The client doesn't typically give you an error because 
it will still fallback and authenticate via Kerberos or Pseudo.  However, this 
is inefficient.

This appears to be due to HADOOP-10301, which made an incompatible change with 
how the AuthHandler tells the Authenticator when a token has expired.  It used 
to give a 401 when the token expired, but now it will do SPNEGO (if you have 
Kerberos credentials) and return a new token, all in the same call.  Oozie 
client's code doesn't handle that case.

With Pseudo Auth, it behaves a little differently and you now get a 403 on that 
first call, but it doesn't give you a new token.
