Using Scala version 2.11.12, OpenJDK 64-Bit Server VM, 1.8.0_242
Branch HEAD

Type --help for more information.

Note it's using scala version 2.11.12. However, my app is using 2.12.8 and this is throwing me the well known java.lang.NoSuchMethodError: scala.Product.$init$(Lscala/Product;)V error.

My question is how to make my spark 2.4.5 use scala 2.12 as indicated in their official webiste under Download section: Spark 2.4.5 uses Scala 2.12

I tried brew search apache-spark and got

Appreciate if any advice is given!

Answer 1

You can build any custom version of Spark locally.

• Clone https://github.com/apache/spark locally
• Update pom file, focusing on scala.version, hadoop.version, scala.binary.version, and artifactId in https://github.com/apache/spark/blob/master/pom.xml
• mvn -DskipTests clean package (from their README)
• After successful build, find all jars in assembly/target/scala-2.11/jars, external/../target, and other external jars you desire, which may be in provided scope of your jars submitted.
• Create a new directory and export SPARK_HOME="/path/to/directory_name" so that https://github.com/apache/spark/blob/master/bin/spark-submit will detect it (see the source to see why)
• Copy the jars into $SPARK_HOME/jars and make sure there are no conflicting jars
• The bin/ scripts should be the same, but if needed, specifically reference those and possibly even unlink the brew ones if you no longer need them

Spark community provides older versions of spark in this website, you can choose any version according your OS, For windows you can use tgz extension file.
