Jeff Zhang commented on FLINK-17788:
------------------------------------
[~kkl0u] The phenomenon I see is that when I launch scala-shell in yarn mode,
it would launch one yarn app for flink yarn session cluster. Then I type some
flink code to trigger one flink, then it would launch another yarn app. The
root cause is that the deployment option is set to yarn-per-job which is
incorrect. Actually deployment option would be set 2 times which cause the
wrong setting.

This is not a clean fix, I think the whole flink scala shell module need to be
refactoring to make the code clean.
