Subject [jira] [Commented] (MAPREDUCE-6304) Specifying node labels when submitting MR jobs
Date Tue, 05 May 2015 01:06:07 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14527701#comment-14527701

Naganarasimha G R commented on MAPREDUCE-6304:
----------------------------------------------

hi [~Wangda], 
I meant actually only deletion of  {{<value></value>}}  for example 
{quote}
<property>
	  <name>mapreduce.job.am.node-label-expression</name>
	 {color:red} <!-- value></value -->{color}
	  <description>Overrides mapreduce.job.node-label-expression for application
	  master containers
	  </description>
</property>
{quote}
which is similar to the existing configs like yarn.ipc.*.factory.class, yarn.resourcemanager.cluster-id,yarn.resourcemanager.ha.rm-ids,yarn.resourcemanager.ha.id
....
In general your approach is fine but as we can make use of the above approach of configuration
did not want to bring in additional default configs. thoughts ?

> Per the discussion on YARN-796, we need a mechanism in MAPREDUCE to specify node labels
when submitting MR jobs.
