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
> Need additional properties to control size of mapper and reducer containers
> independently for tez tasks.
