Prashant Sharma updated SPARK-15942:
------------------------------------
Description:
As a follow up for SPARK-15697, I have following semantics for `:reset` command.
On `:reset` we forget all that user has done but not the initialization of
spark. To avoid confusion or make it more clear, we show the message `spark`
and `sc` are not erased, infact they are in same state as they were left by
previous operations done by the user.
While doing above, somewhere I felt that this is not usually what reset means.
But an accidental shutdown of a cluster can be very costly, so may be in that
sense this is less surprising and still useful.
