David Kjerrumgaard updated HIVE-8255:
-------------------------------------
    Description: 
There were 2 memory related configuration properties added in HIVE-6037, hive.tez.container.size & hive.tez.java.opts. 

These settings apply to BOTH the mapper and reducer tasks in a TEZ job. Usually, the amount of memory required for your map tasks varies greatly from the memory requirements for your reducers. Therefore, it would be better if the hive.tez.container.size & hive.tez.java.opts properties were replaced with map and reduce specific ones, e.g.

hive.tez.map.container.size & hive.tez.map.java.opts
hive.tez.reduce.container.size & hive.tez.reduce.java.opts
