I am trying to connect Knime Desktop to my EMR Spark cluster, but I am constantly getting the following error when I am trying to create the spark context.
Execute failed: Failed to create Livy session. Please consult the Livy server log. (Exception)
Here is my Spark cluster info,
Release label: emr-5.9.0
Applications: Hue 4.0.1, Spark 2.2.0, Zeppelin 0.7.2, Livy 0.4.0
The livy server logs are also attached to this topic.
