Subject [jira] [Created] (SPARK-19757) Executor with task scheduled could be killed due to idleness
Date Tue, 28 Feb 2017 00:15:45 GMT
Jimmy Xiang created SPARK-19757:
-----------------------------------

             Summary: Executor with task scheduled could be killed due to idleness
                 Key: SPARK-19757
                 URL: https://issues.apache.org/jira/browse/SPARK-19757
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 1.6.0
            Reporter: Jimmy Xiang
            Priority: Minor


With dynamic executor allocation enabled on yarn mode, after one job is finished for a while,
submit another job, then there is race between killing idle executors and scheduling new task
on these executors. Sometimes, some executor is killed right after a task is scheduled on
it.
