Jon Maurer created SPARK-13412:
----------------------------------
Summary: 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
