Description

Could we please see some more documentation around the yarn.app.mapreduce.am.resource.mb parameter in mapred-site.xml? Information about when (if ever) it would be appropriate to increase or decrease the value of this would be useful.

Is there a minimum value this needs to be set in order for MapReduce jobs to run under YARN?
