> PySpark RDDs are missing the distinct(n) method
> -----------------------------------------------
>
> Key: SPARK-3519
> URL: https://issues.apache.org/jira/browse/SPARK-3519
> Project: Spark
> Issue Type: Bug
> Components: PySpark, Spark Core
> Affects Versions: 1.1.0
> Reporter: Nicholas Chammas
> Assignee: Matthew Farrellee
>
> {{distinct()}} works but {{distinct(N)}} doesn't.
> {code}
> >>> sc.parallelize([1,1,2]).distinct()
> PythonRDD[15] at RDD at PythonRDD.scala:43
> >>> sc.parallelize([1,1,2]).distinct(2)
> Traceback (most recent call last):
> File "<stdin>", line 1, in <module>
> TypeError: distinct() takes exactly 1 argument (2 given)
> {code}
> The PySpark docs only call out [the {{distinct()}}
> signature|http://spark.apache.org/docs/1.1.0/api/python/pyspark.rdd.RDD-class.html#distinct],
> but the programming guide [includes the {{distinct(N)}}
> signature|http://spark.apache.org/docs/1.1.0/programming-guide.html#transformations]
> as well.
