      Description

      Hi,

      I have setup Python interpreter connected to Anaconda Python2, initially jobs when submitted where waiting in FIFO and got to know that Zeppelin provides two scheduler modes.
      1 FIFO
      2.Parallel

      So , I made the changes in PythonInterpreter.java to use SchedulerFactory.singleton().createOrGetParallelScheduler instead of FIFO.

      The change though schedules jobs concurrently , I observe that when a long running jobs is scheduled it hold other smaller jobs which ideally should finish with no dependency ex. user 1 schedules %python
      import scipy
      scipy.test()

      user 2 schedules %python
      print ("Hello World")

      The job run by user 2 waits till job of user1 complete.

      Please advise.

      Thanks
      Vamsi
