> Spark Shell Ctrl-C behaviour suggestion
> ---------------------------------------
>
> Key: SPARK-13412
> URL: https://issues.apache.org/jira/browse/SPARK-13412
> Project: Spark
> Issue Type: Improvement
> Components: Spark Shell
> Affects Versions: 1.6.0
> Reporter: Jon Maurer
> Priority: Minor
>
> It would be useful to catch the interrupt from a ctrl-c and prompt for
> confirmation prior to closing spark shell. This is currently an issue when
> sitting at an idle prompt. For example, if a user accidentally enters ctrl-c
> then all previous progress is lost and must be run again. Instead, the
> desired behavior would instead prompt the user to enter 'yes' or another
> ctrl-c to exit the shell, thus preventing rework.
> There is related discussion about this sort of feature on the Scala issue
> tracker: https://issues.scala-lang.org/browse/SI-6302
