---------------------------------
Yeah, you are right. Will deliver a PR soon. Thanks!
> numPartitions argument to sqlContext.range() should be optional
> ----------------------------------------------------------------

> Key: SPARK-12150
> URL: https://issues.apache.org/jira/browse/SPARK-12150
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Reporter: Henri DF
> Priority: Minor
>
> It's a little inconsistent that the first two sqlContext.range() methods
> don't take a numPartitions arg, while the third one does.
> And more importantly, it's a little inconvenient that the numPartitions arg
> is mandatory for the third range() method - it means that if you want to
> specify a step, you suddenly have to think about partitioning - an orthogonal
> concern.
> My suggestion would be to make numPartitions optional, like it is on the
> sparkContext.range(..).
