----------------------------------
Summary: Improve the container placement strategy by considering
the localities of pending container requests
Key: SPARK-9817
URL: https://issues.apache.org/jira/browse/SPARK-9817
Project: Spark
Issue Type: Improvement
Components: YARN
Reporter: Saisai Shao
Priority: Minor
Current implementation does not consider the localities of pending container
requests, since required locality preferences of tasks will be shifted time to
time. It is better to discard outdated container request and recalculate with
container placement strategy.
