> *Preconditions:*
> 1. Jupyter is created
> *Steps to reproduce:*
> # Run playbook via kernel R (Local SparkR (R-3.4.4, Spark-2.4.4) and remote
> EMR5.28 SparkR (R-3.4.1, Spark-2.4.4))
> # Run playbook via kernel Scala (Local Apache Toree - Scala (Scala-2.11.12,
> Spark-2.4.4) and remote EMR 5.28 Apache Toree - Scala (Scala-2.11.12,
> Spark-2.4.4) )
> *Actual result:*
> # Connection to kernel R died
> # Connection to Scala stuck
> *Expected result:*
> 1. Connection to kernel R is successful
> 2. Connection to Scala is successful
> *For AWS*
