[jira] [Updated] (YARN-2884) Proxying all AM-RM communications

["Kishore Chaliparambil (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/YARN-2884?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Kishore Chaliparambil updated YARN-2884:
----------------------------------------
    Attachment: YARN-2884-V12.patch

This patch fixes the issue with rolling Tokens in the proxy service. I tested the rolling tokens feature by setting the time interval to a smaller value and submitting long running job as a different user. The jobs finished successfully. 

The unused methods from the AMRMProxyTokenSecretManager has been removed too.

I will create a new JIRA for adding test cases with some simulations for clusters and proxy.

> We introduce the notion of an RMProxy, running on each node (or once per rack). Upon start the AM is forced (via tokens and configuration) to direct all its requests to a new services running on the NM that provide a proxy to the central RM. 
> This give us a place to:
> 1) perform distributed scheduling decisions
> 2) throttling mis-behaving AMs
> 3) mask the access to a federation of RMs
