[jira] [Created] (SPARK-4236) External shuffle service must cleanup its shuffle files

Aaron Davidson created SPARK-4236:
-------------------------------------

             Summary: External shuffle service must cleanup its shuffle files
                 Key: SPARK-4236
                 URL: https://issues.apache.org/jira/browse/SPARK-4236
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 1.2.0
            Reporter: Aaron Davidson
            Priority: Critical


When external shuffle service is enabled, executors no longer cleanup their own shuffle files, as the external server can continue to serve them. The external serer must clean these files up once it knows that they will never be used again (i.e., when the application terminates or when Spark's ContextCleaner requests that they be deleted).
