    @ScrapCodes I think the original scaladoc explains that this performs a shuffle, but you
didn't copy this code in any of the python/java docs. Would you mind adding that? It's sort
of important because otherwise people could think this is a cheap operation.
    ```
      /**
       * Return the intersection of this RDD and another one. The output will not contain
any duplicate
       * elements, even if the input RDDs did.
       *
       * Note that this method performs a shuffle internally.
       */
    ```
