Navis created HIVE-11518:
----------------------------
Summary: Provide interface to adjust required resource for tez
tasks
Key: HIVE-11518
URL: https://issues.apache.org/jira/browse/HIVE-11518
Project: Hive
Issue Type: Improvement
Components: Query Processor
Reporter: Navis
Assignee: Navis
Priority: Minor
Resource requirements for each tasks are varied but currently it's fixed to one
value(via hive.tez.container.size). It would be good to customize resource
requirements appropriate to expected work.
Suggested interface is quite simple.
{code}
public interface ResourceCalculator {
Resource adjust(Resource resource, MapWork mapWork);
Resource adjust(Resource resource, ReduceWork reduceWork);
}
{code}
