Subject [jira] [Commented] (MAPREDUCE-5189) Basic AM changes to support preemption requests (per YARN-45)
Date Mon, 13 May 2013 23:41:16 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5189?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13656534#comment-13656534

Carlo Curino commented on MAPREDUCE-5189:

Updating the patch to reflect the evolved and committed YARN-45. (This is a minimum patch
to match YARN-45, 
with MAPREDUCE-5196 and MAPREDUCE-5197 we provide a more interesting handling preemption based
on checkpointing).
