[jira] [Created] (SYSTEMML-1433) Blocking rdd and broadcast cleanup

Matthias Boehm created SYSTEMML-1433:
----------------------------------------

             Summary: Blocking rdd and broadcast cleanup
                 Key: SYSTEMML-1433
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1433
             Project: SystemML
          Issue Type: Bug
            Reporter: Matthias Boehm


Our SparkExecutionContext has an internal configuration {{ASYNCHRONOUS_VAR_DESTROY}} that indicates if rdds and broadcasts should be cleaned up in an asynchronous manner (true by default). However, it is incorrectly fed to the respective unpersist and destroy calls as a {{blocking}} parameter, which essentially makes all cleanup calls unwillingly synchronous.
