> Project: Apache Lens
> Issue Type: Sub-task
> Components: server
> Reporter: Amareshwari Sriramadasu
> Assignee: Jaideep Dhok
> Fix For: 2.1

>
> We are estimating the cost of query on each driver sequentially. Since each
> estimate is independent those can be parallelized.
> For each driver rewrite the query, call driver.estimate - need to parallelize
> this for all drivers.
