Description

Preconditions:

1. Jupyter is created

Steps to reproduce:

1. 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))
2. 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:

1. Connection to kernel R died
2. Connection to Scala stuck

Expected result:

1. Connection to kernel R is successful

2. Connection to Scala is successful
