             Summary: line editing in scala shell
                 Key: FLINK-2709
                 URL: https://issues.apache.org/jira/browse/FLINK-2709
             Project: Flink
          Issue Type: New Feature
          Components: Scala Shell
            Reporter: Matthew Farrellee


it would be very helpful to be able to edit lines in the shell. for instance, up/down arrow to navigate history and left/right to navigate a line.

bonus for history search and advanced single line editing (e.g. emacs bindings)
