[SPARK-4470] Validate number of threads in local mode
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.
Fix for [SPARK-4470](https://issues.apache.org/jira/browse/SPARK-4470).
