> When a select query is triggered, driver will prune the segments and give a list of blocklets that need to be scanned. The number of tasks from spark will be equal to the number of blocklets identified.
> In case where one task has more than one blocklet for same file, then BlockExecution getting formed is incorrect. Due to this the query results are incorrect.
