             Summary: ClassCastException due to wrong execution context w/ parfor spark and forced singlenode
                 Key: SYSTEMML-1386
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1386
             Project: SystemML
          Issue Type: Bug
            Reporter: Matthias Boehm


Generally, we allow that users force singlenode execution type but for example a remote_mr or remote_spark parfor execution. For parfor remote_spark, this currently fails with the following stracktrace due to a wrong execution context.

Caused by: java.lang.ClassCastException: org.apache.sysml.runtime.controlprogram.context.ExecutionContext cannot be cast to org.apache.sysml.runtime.controlprogram.context.SparkExecutionContext
