Hi Rakesh, Internally Hive does support list of maps, and even more nested levels.
However, we didn't open it up for the "create table" command yet. That shouldn't be hard to do though. We will require the list to be separated by ^B, and map items to be separated by ^C, while map key and value separated by ^D. Is that a format that you can produce?
