Thanks for your response. 

Is the Cloudera to Databricks extraction a one-time migration, or would this be something you do regularly?  That would change the strategy.

-So we are evaluating the option but it would be onetime to begin with but would be interesting to know how will the strategy differ incase of incremental loads. 

So in case of Databricks express set up , do we still need to have AWS S3 bucket for storage.
