Balu Vellanki commented on FALCON-748:
--------------------------------------

The code changes look good. I submitted a new patch that has documentation for the newly added
startup property "falcon.jetty.request.buffer.size"

> 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/)
