Github user Leemoonsoo commented on the issue: https://github.com/apache/zeppelin/pull/1366 Thanks @zjffdu for the fix. Spark sets `-classpath` with not only `spark.jars` but also `spark.yarn.dist.jars` in case of master is `yarn`. see https://github.com/apache/spark/blob/v2.0.0/repl/scala-2.11/src/main/scala/org/apache/spark/repl/Main.scala#L57 https://github.com/apache/spark/blob/v2.0.0/core/src/main/scala/org/apache/spark/util/Utils.scala#L2411 Do you think Zeppelin need to do the same?
