[jira] [Commented] (MAPREDUCE-3359) Yarn clients / AM should be able to provide config options to the RM / NM

["Siddharth Seth (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3359?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13144297#comment-13144297 ] 

Siddharth Seth commented on MAPREDUCE-3359:
-------------------------------------------

This could be a key-value list in the ContainerLaunchContext (ApplicationSubmissionContext would be better but that isn't available to the NM).
An alternate would be to add individual properties - like setLogAggPolicy(), setCancelTokenOnAppComplete. This list would just end up growing though, so prefer the first option.

> The RM and NM do not read a job's configuration. Clients / AMs should however be able to configure certain parameters for the RM/NM on a per app basis - like the Log Retention policy, token cancellation.
