[jira] [Created] (SPARK-4280) In dynamic allocation, add option to never kill executors with cached blocks

Sandy Ryza created SPARK-4280:
---------------------------------

             Summary: In dynamic allocation, add option to never kill executors with cached blocks
                 Key: SPARK-4280
                 URL: https://issues.apache.org/jira/browse/SPARK-4280
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 1.2.0
            Reporter: Sandy Ryza


Even with the external shuffle service, this is useful in situations like Hive on Spark where a query might require caching some data. We want to be able to give back executors after the job ends, but not during the job if it would delete intermediate results.
