Subject [jira] [Reopened] (YARN-2603) ApplicationConstants missing HADOOP_MAPRED_HOME
Date Thu, 13 Nov 2014 16:07:34 GMT

     [ https://issues.apache.org/jira/browse/YARN-2603?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vinod Kumar Vavilapalli reopened YARN-2603:
-------------------------------------------

This is not correct. We deliberately avoided putting compile time references to MapReduce
in all of YARN.

You should instead use yarn.nodemanager.env-whitelist and set HADOOP_MAPRED_HOME while starting
nodemanager.

OTOH, we are moving away from cluster installs of MapReduce to instead use DistributedCache:
See MAPREDUCE-4421.

I am going to wait a couple of hours before reverting this.
