> 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.
