Jason Lowe updated MAPREDUCE-4421:
----------------------------------
Attachment: MAPREDUCE-3927-4.patch
One minor tweak to the documentation where we need to add $HADOOP_CONF_DIR to
the full tarball classpath case otherwise the job will not run on a secure
cluster. UserGroupInformation has a static block that loads the security
details from a new Configuration, so for now we still need to pick up the
security settings from the node's configs.
> Remove dependency on deployed MR jars

> Currently MR AM depends on MR jars being deployed on all nodes via implicit
> dependency on YARN_APPLICATION_CLASSPATH.
> 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.
