Summary: Kill other task attempts when one taskattempt belonging
the same task is succeeded in speculation
Key: SPARK-10530
URL: https://issues.apache.org/jira/browse/SPARK-10530
Project: Spark
Issue Type: Improvement
Components: Scheduler, Spark Core
Reporter: Jeff Zhang
Currently when speculation is enabled, other task attempts won't be killed if
one task attempt in the same task is succeeded, it is not resource efficient,
it would be better to kill other task attempts when one taskattempt belonging
the same task is succeeded in speculation.
