[jira] [Created] (PIG-4555) Add -XX:+UseNUMA for Tez jobs

Rohini Palaniswamy created PIG-4555:
---------------------------------------

             Summary: Add -XX:+UseNUMA for Tez jobs
                 Key: PIG-4555
                 URL: https://issues.apache.org/jira/browse/PIG-4555
             Project: Pig
          Issue Type: Improvement
            Reporter: Rohini Palaniswamy
            Assignee: Rohini Palaniswamy
             Fix For: 0.15.0


    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.
