Mapreduce job utilizing more heap on hdp 3.0

New Contributor
I have a job which runs on hadoop 2.9 with 1 gb mapper memory but same job need at least 4 gb to run on HDP 3.0. Both clusters have almost similar configs and no changes to job or any major parameters.


Let me know if you need any further info.
