[jira] [Created] (SPARK-15942) Unblock `:reset` command in REPL.

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.
