Prashant Sharma created SPARK-15942:
---------------------------------------
Summary: Unblock `:reset` command in REPL.
Key: SPARK-15942
URL: https://issues.apache.org/jira/browse/SPARK-15942
Project: Spark
Issue Type: Bug
Reporter: Prashant Sharma
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 more clear, we show the message `spark` and
`sc` are not erased, infact they are in same state as they were left by
previous operation 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.
