Hi all, I came across the same problem as http://mail-archives.apache.org/mod_mbox/incubator-zeppelin-users/201509.mbox/%3CCAPKgQ9rBh6tYFXYm5sQDEkfcmdp-gxsHoQ-pX6Ovwpuh-J=o...@mail.gmail.com%3E
When I launched the Zeppelin on Yarn, the application log always tells me that Error: Could not find or load main class org.apache.spark.deploy.yarn.ExecutorLauncher Then I checked the 'spark.yarn.jar="${ZEPPELIN_HOME}/interpreter/spark/zeppelin-spark-0.6.0-incubating-SNAPSHOT.jar" ' and found that this class is not included. Afterwards, I changed my configuration to '"spark.yarn.jar=${SPARK_HOME}/lib/spark-assembly-1.3.0-hadoop2.4.0.jar". It works!!! My Zeppelin is with the latest commit on Oct 5,2015. My Spark version is 1.3.0 and Hadoop version is 2.6.0. I hope someone can help update the 'zeppelin-spark-${VERSION}-incubating-SNAPSHOT.jar' so that it includes all necessary classes. Regards, Ge
