             Summary: Falcon throws '413 Full Head' error message when kerberos is enabled with AD
                 Key: FALCON-748
                 URL: https://issues.apache.org/jira/browse/FALCON-748
             Project: Falcon
          Issue Type: Bug
    Affects Versions: 0.5
            Reporter: Venkatesh Seetharam
            Priority: Critical
             Fix For: 0.6


PROBLEM:  Customer has Kerberos setup with AD, and when using ambari-qa or other users of HDP, we are able to get the required details but using the AD users receiving the exception '413, message: FULL head'

IMPACT:   This makes falcon unusable for replication as the AD users cannot access falcon

STEPS TO REPRODUCE:  
1.  Set up AD user and Kerberos pointing to AD users
2.  Enable Kerberos for the HDP cluster.
3.  Try to run the falcon admin -version command, you would see the issue.

ACTUAL BEHAVIOR:  Receiving '413, message: FULL head' when trying to access falcon. 
EXPECTED BEHAVIOR:   The exception should not occur.

1.  The reason for this exception is because of the header buffer size being limited in our embedded Jetty for Falcon.  
2.  Found a blog which states what needs to be set  (http://blog.richeton.com/2010/03/11/set-jetty-buffer-size-maven/)
