-------------------------------------------------------------

Prototyped with RestCsrfPreventionFilter in Hadoop 2.8.0. Tested with empty 
header and CSRF filter enabled that GET methods get accepted while POST methods 
are rejected as expected. See attached picture. If we use 
RestCsrfPreventionFilter, it requires Falcon to upgrade Hadoop version to 
2.8.0. Let me know if there is any objection on this. Thank you!
