Let us say I have the following two RDDs, with the following key-pair values.

    rdd1 = [ (key1, [value1, value2]), (key2, [value3, value4]) ]

and 

    rdd2 = [ (key1, [value5, value6]), (key2, [value7]) ]

Now, I want to join them by key values, so for example I want to return the following

    ret = [ (key1, [value1, value2, value5, value6]), (key2, [value3, value4, value7]) ] 

How I can I do this, in spark using python or scala? One way is to use join, but join would create a tuple inside the tuple. But I want to only have one tuple per key value pair.
