>             Project: Spark
>          Issue Type: Wish

>    Affects Versions: 1.3.1
>         Environment: YARN

> When ctrl-c is pressed in shell, behaviors are not consistent across spark-sql, spark-shell, and pyspark resulting in confusion for users. Here is the summary-
> ||shell||after ctrl-c|
> |spark-sql|cancels the running job|
> |spark-shell|exits the shell|
> |pyspark|throws error \[1\] and doesn't cancel the job|
> Particularly, pyspark is worst because it gives a wrong impression that the job is cancelled although it is not.
> Ideally, every shell should act like {{spark-sql}} because it allows users to cancel the running job while staying in shell. (Pressing ctrl-c twice exits the shell.) 
> \[1\] pyspark error for ctrl-c
> {code}
> Traceback (most recent call last):
