Subject [jira] [Commented] (MAPREDUCE-2746) [MR-279] [Security] Yarn servers can't communicate with each other with hadoop.security.authorization set to true
Date Sat, 22 Oct 2011 20:08:32 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2746?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13133460#comment-13133460
] 

Mahadev konar commented on MAPREDUCE-2746:
------------------------------------------

Looks good to me.
Minor nit, might want to change the variable name in MRAMPolicyProvider.java
{code}
+  private static final Service[] nodeManagerServices = 
{code}

Trying it on a secure cluster.

> 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).
> [~devaraj] also found this issue independently.
