Harsh J commented on MAPREDUCE-4421: ------------------------------------ Thanks Kihwal and Arun. I guess if its via a central, i.e., a dist-cache, we may lose some heterogenous cluster abilities (different OS versions forming a single cluster, with a chance that one's natives may not work on the other and needs uniquely compiled sets for each). Not much of a worry, and I've hardly seen folks do this in the long run, but might be worth providing a solution for, in the future? > Remove dependency on deployed MR jars > ------------------------------------- > > Key: MAPREDUCE-4421 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-4421 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Affects Versions: 2.0.0-alpha > Reporter: Arun C Murthy > Assignee: Arun C Murthy > > 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. -- This message is automatically generated by JIRA.
