Subject [jira] [Commented] (MAPREDUCE-3359) Yarn clients / AM should be able to provide config options to the RM / NM
Date Fri, 04 Nov 2011 20:27:52 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3359?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13144312#comment-13144312

Mahadev konar commented on MAPREDUCE-3359:
------------------------------------------

I think key value pairs are too generic and can get very confusing to make sense of. I dont
think we'll be adding too many such options to the launch context, so I'd prefer an API to
make it explicit and less confusing to use.

> 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.
