> HIVE-16552 gives admin an option to control the maximum number of tasks a 
> Spark job may have. However, this may not be sufficient as this tends to 
> penalize jobs that have many stages while favoring jobs that has fewer 
> stages. Ideally, we should also limit the number of tasks in a stage, which 
> is closer to the maximum number of mappers or reducers in a MR job.
