   This problem persists in the current master. I believe the PR from @akitanaka is needed to solve this problem
   ```

           at org.apache.livy.utils.SparkYarnApp$$anon$1.run(SparkYarnApp.scala:78)

   ```
   And then I see the exact same issue that @akitanaka describes, i.e. the Livy session remains in `starting` state.
