> Add -XX:+UseNUMA for Tez jobs

>
> For very big Tez jobs (~50K tasks), AM quickly goes OOM without
> -XX:+UseNUMA. tez.am.launch.cmd-opts default setting has that, but since pig
> gives preference to yarn.app.mapreduce.am.command-opts if present (which
> usually it is), -XX:+UseNUMA is not there. Need to add -XX:+UseNUMA if we
> are picking up mapreduce setting.
