Thanks a lot for very prompt response. Then next questions are the following.
1. Can we conclude that Spark is NOT the solution for our requirement? Or 2. Is there a design approach to meet such requirements using Spark?

You can create new RDD containing updated entries(often not what you want to do).

We have operations that update RDDs by way of adding entries to the map, delete entries from the map as well as update value part of maps. We also have map reduce functions that operate on the RDDs.The questions are the following. 1. Can RDDs be updated? if Yes, what rae the methods? 2. If we update RDDs, will it happen in place or does it create new RDDs with almost double the original RDD size (original+newly created RDD)? Thank you very much.
