            How to solve SBT Dependency Problem with Spark and whisklabs/docker-it-scala
            Asked 2019-Aug-20 at 06:19

            I have written a spark structured streaming app (I'm using Scala with sbt) and now I have to create an integration test. Unfortunately I'm running into a dependency problem I can't solve. I'm using scala with sbt.

            My dependency looks like the following

            I tried two approaches

            1. Approach: Shading the dependency in the xxxxxxx project

            I added the assembly plugin to the plugin.sbt

            • addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.7")

            and added some shading rules to the build.sbt. I was creating a fat-jar for the xxxxxxx project

            I am building a Spark application with bash script and I have an only spark-sql and core dependencies in the build.sbt file. So every time I call some rdd methods or convert the data to case class for dataset creation I get this error:

            Not sure what was the problem exactly, however, I have recreated the project and moved the source code there. The error disappeared

            NoSuchMethodError: org.apache.spark.internal.Logging
            Asked 2019-Jan-09 at 11:48

            I'm trying to run an application made up with spark structured streaming - data input from kafka. Spark version is 2.4.0, scala version is 2.12.7. And I'm making multiple fat-jar using sbt - my project is multi-module project. Building jar is not a problem. When I try to spark-submit with my jar, NoSuchMethodError is occured.

            1. I removed provided scope from spark-sql-kafka-0-10.

            val sparkSqlKafka = "org.apache.spark" %% "spark-sql-kafka-0-10" % sparkVersion

            1. In assemblyMergeStrategy I added line below.

            case "META-INF/services/org.apache.spark.sql.sources.DataSourceRegister" => MergeStrategy.concat

            This is whole error log.

            The warning during your project's compilation step hints that Java 9+ is used. For details about the new module system see this SO answer.

            With Java 8 set, your demo project runs just fine, whereas Java 10 fails with the error you've described. I'd expect the same error for any JDK 9+ version.
