Subject [jira] [Updated] (MAPREDUCE-4421) Run MapReduce framework via the distributed cache
Date Tue, 01 Oct 2013 22:02:26 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-4421?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jason Lowe updated MAPREDUCE-4421:

    Summary: Run MapReduce framework via the distributed cache  (was: Remove dependency on
deployed MR jars)

Updating the title to describe the change being committed since it does not completely remove
the dependency on deployed MR jars. This change still relies on the job client and ShuffleHandler
that was deployed to the cluster.

> Currently MR AM depends on MR jars being deployed on all nodes via implicit dependency
> We should stop adding mapreduce jars to YARN_APPLICATION_CLASSPATH and, probably, just
rely on adding a shaded MR jar along with job.jar to the dist-cache.
