---------------------------------------
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.
