> Awesome! that is a great news. Just out of curiosity, does the Zeppelin
server in KB must be the one which has acess to the Spark_Home or the Spark
interpreter which is now a pod? (Just to manage which one should be a gateway
in Cloudera cluster).
Spark Interpreter is running inside of its own Pod. And Spark driver is
running in Spark Interpreter. So Spark Interpreter Pod is the one, who need
SPARK_HOME and access from/to Spark master/executors in your cluster.
