I've been struggling with a particularly puzzling issue after upgrading to Spark 1.5.1 from Spark 1.4.1.

For those that are interested, a full repro and logs follow. --- I am running this on Spark 1.5.1+Hadoop 2.6. I have tried this in various combinations of * local/standalone mode * putting mysql on the classpath with --jars/building a fat jar with mysql in it/manually running sc.addJar on the mysql jar * --deploy-mode client/--deploy-mode cluster but nothing seems to change. Here is an example invocation, and the accompanying source code: The source code: And the build.sbt: And here are the results when run against Spark 1.4.1 (build.sbt has been updated accordingly) -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/new-1-5-1-behavior-exception-on-executor-throws-ClassNotFound-on-driver-tp25124.html Sent from the Apache Spark User List mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
