Subject [jira] [Commented] (MAPREDUCE-3315) Master-Worker Application on YARN
Date Thu, 24 May 2012 06:54:42 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13282237#comment-13282237
] 

Sharad Agarwal commented on MAPREDUCE-3315:
-------------------------------------------

I meant the later one. The only difference is that I think it is better to not expose HeartbeatRequest
and HeartbeatResponse to users beacause certain fields like actions etc are framework level.
Instead these classes should composes the fields required by the user.

> Currently master worker scenarios are forced fit into Map-Reduce. Now with YARN, these
can be first class and would benefit real/near realtime workloads and be more effective in
using the cluster resources.
