Description

Currently there's a way to configure container size for tez as well as java opts to start containers.

However, if you only set container size and not java opts, we fall back to MR settings for java opts which will likely fail (killed by yarn).

vcores is always taken from the MR settings. Need to have a way to overwrite that too.

Tez 0.5 and onwards will automatically generate the right java opts string when the container/cpus are specified. This is preferable to falling back to MR.
