Subject [jira] [Resolved] (YARN-501) Application Master getting killed randomly reporting excess usage of memory
Date Fri, 22 Mar 2013 15:53:15 GMT

     [ https://issues.apache.org/jira/browse/YARN-501?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ravi Prakash resolved YARN-501.
-------------------------------

    Resolution: Not A Problem

Hi Krishna,

Please set yarn.app.mapreduce.am.command-opts to include a more reasonable -Xmx. Or perhaps
increase yarn.nodemanager.vmem-pmem-ratio to a higher ratio if you don't need that much physical
memory.
