Hi @smarthi , @steveblackmon ,

Thanks for the review.
I have refactored the code to handle the following issues:

- removing of guava APIs.
- no types specified in RHS.
- Switch to TestNG in IT tests
- used `streamsDatum.getMetadata().get("id")` if it exists, enabling an 
stream to get a write-then-overwrite behavior when the id is already known
- supported an array of strings for host

perhaps this should be an array of strings, so module can start-up with
