Subject [jira] [Created] (SPARK-4139) Start the number of executors at the max if dynamic allocation is enabled
Date Wed, 29 Oct 2014 20:35:34 GMT
Andrew Or created SPARK-4139:
--------------------------------

             Summary: Start the number of executors at the max if dynamic allocation is enabled
                 Key: SPARK-4139
                 URL: https://issues.apache.org/jira/browse/SPARK-4139
             Project: Spark
          Issue Type: Improvement
          Components: YARN
    Affects Versions: 1.2.0
            Reporter: Andrew Or
            Assignee: Andrew Or


SPARK-3795 allows us to dynamically scale the number of executors up and down. We should start
the number at the max instead of from 0 in the beginning, because the first job will likely
run immediately after the SparkContext is set up.
