Found that HADOOP-6184 <https://issues.apache.org/jira/browse/HADOOP-6184>is exactly what i want but the thing is I am running CDH3u0 which is 0.20.2 based. I wonder if anyone here have a magic to dump the hadoop configuration; doesn't need to be json as long as i can check if what i changed in configuration file is really kicked in. PS, i change this "mapred.user.jobconf.limit" -P This e-mail message may contain privileged and/or confidential information, and is intended to be received only by persons entitled to receive such information.
