> Hive driver wait time is fixed for task getting executed in parallel.

> Project: Hive

> Reporter: mahesh kumar behera

> Priority: Major
> Labels: pull-request-available

> During a command execution hive driver executes the task in a separate thread
> if the task to be executed is set as parallel. After starting the task,
> driver checks if the task has finished execution or not. If the task
> execution is not finished it waits for 2 seconds before waking up again to
> check the task status. In case of task with execution time in milliseconds,
> this wait time can induce substantial overhead. So instead of fixed wait
> time, exponential backedup sleep time can be used to reduce the sleep
> overhead. The sleep time can start with 100ms and can increase up to 2
> seconds doubling on each iteration.
