Hi, Many thanks for the suggestions. I discovered that the problem was related on a missing driver definition in the jdbc options map. The error wasn’t really helpful to understand that!

I've recently spent a lot of time researching a problem similar to yours with Spark 1.6.1 (Scala). For us the collision was related to class version in org.jboss.netty.handler.ssl package. I think there are three ways to solve this: 1) Check jar versions for jars deployed as part of Spark runtime and use the same versions in your code 2) Update your Spark runtime libs (if you can) with versions of jars that work (that can be tricky) 3) The solution we used was to add shading configuration (in Build.scala) for packages that were colliding: val shadingRules = Seq(ShadeRule.rename("org.jboss.netty.handler.ssl.**" -> "shadeit.@1").inAll) assemblyShadeRules in assembly := shadingRules That last option worked best because it allowed us to control version collision for multiple packages/classes. I don't know if you're using Scala or Java but maybe this gives you some ideas on how to proceed. Fixing class version collision can be a messy ordeal, you'll need to move jars/versions around until it works. It looks like Maven also has a shading plugin so if you're using Java maybe you can try that: https://maven.apache.org/plugins/maven-shade-plugin/ Best, M ________________________________ If you reply to this email, your message will be added to the discussion below: http://apache-spark-user-list.1001560.n3.nabble.com/Spark-SQL-NoSuchMethodException-DriverWrapper-init-tp27171p27211.html To unsubscribe from Spark SQL NoSuchMethodException...DriverWrapper.<init>(), click here<http://apache-spark-user-list.1001560.n3.nabble.com/template/NamlServlet.jtp?macro=unsubscribe_by_code&node=27171&code=bWlya28uYmVybmFyZG9uaUBpeHh1cy5jb218MjcxNzF8LTEwMzI1MDE1MTI=>.
