flink-scala

This module is a replacement for the org.apache.flink:flink-scala lib shipped with flink distribution, and allows using Flink with Scala 2.13.

For more refer to https://issues.apache.org/jira/browse/FLINK-13414.

Replacing flink-scala in flink distribution

rm $FLINK_HOME/lib/flink-scala*.jar

wget https://repo1.maven.org/maven2/pl/touk/flink-scala_2.13/1.1.6/flink-scala_2.13-1.1.6-assembly.jar -O $FLINK_HOME/lib/flink-scala_2.13-1.1.6-assembly.jar

Using as a lib (probably only sufficient when child-first classloading is enabled on flink)

libraryDependencies += "pl.touk" %% "flink-scala" % "1.1.6"

Pre-built Flink images

We provide pre-built Docker images for Flink with Scala 2.13 on Docker Hub.
