Hi all, 

I am current working on a project that requires to transform each RDD in a DStream to a Map. Basically, when we get a list of data in each batch, we would like to update the global map. I would like to return the map as a single RDD.

I am currently trying to use the function transform. The output will be a RDD of the updated map after each batch. How can I create an RDD from another data structure such as Int, Map, ect. Thanks!
