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.
