[MR-279] [Security] Yarn servers can't communicate with each other with
hadoop.security.authorization set to true
-----------------------------------------------------------------------------------------------------------------
Key: MAPREDUCE-2746
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2746
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Reporter: Vinod Kumar Vavilapalli
Fix For: 0.23.0
Because of this problem, till now, we've been testing YARN+MR with
{{hadoop.security.authorization}} set to false. We need to register yarn
communication protocols in the implementation of the authorization related
PolicyProvider (MapReducePolicyProvider.java).
