Hi Team, We have Apache Livy running on EMR . As part of our POC we need to submit spark jobs via Livy . For this we need to build connection from NiFi -> Livy which will submit a session. While connecting to Livy via NiFi we are having issues in ExecuteSparkInteractive , here is the error : LivySessionController[id=5c0f3fbf-f3a8-1dc8-0000-0000432c09c1] Livy Session Manager Thread run into an error, but continues to run: java.lang.NullPointerException We have used telnet command from NiFi nodes directly to connect with Livy and that was working fine but the connection from NiFi is resisting. From the node we are able to submit the Livy session / Spark Job. Thanks, Haider Naveed ... View more
