Hi hadoopers, I was looking the way to dump hadoop configuration in order to check if what i have just changed in mapred-site.xml is really kicked in.
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
