[jira] [Created] (SPARK-4470) SparkContext accepts local[0] as a master URL

Kenichi Maehashi created SPARK-4470:
---------------------------------------

             Summary: SparkContext accepts local[0] as a master URL
                 Key: SPARK-4470
                 URL: https://issues.apache.org/jira/browse/SPARK-4470
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 1.1.0
            Reporter: Kenichi Maehashi
            Priority: Trivial


When running Spark locally, if number of threads is specified as 0 (e.g., {{spark-submit --master local\[0\] ...}}), the job got stuck and does not run at all.
I think it's better to validate the parameter.
