I filed KUDU-3128 <https://issues.apache.org/jira/browse/KUDU-3128> to track adjusting the build to also compile and publish a 2.12 version of kudu-spark.
For now you should be able to build your own by updating the Spark version in dependencies.gradle: https://github.com/apache/kudu/blob/master/java/gradle/dependencies.gradle#L55 To build the Jar, in the java directory, run : *./gradlew :kudu-spark:assemble* *You can also run all the tests with:* *./gradlew :kudu-spark:test* The jar can then be found at: *./kudu-spark/build/libs/kudu-spark2_2.12-{version}.jar* On Thu, May 21, 2020 at 5:17 AM Denis Bolshakov <bolshakov.de...@gmail.com> wrote: > Hello, > > Pavel, my two cents: > looks like information on https://spark.apache.org/docs/2.4.5/: is not > fully correct. > > On download page there is > Download Apache Spark™ > > 1. > > Choose a Spark release: 3.0.0-preview2 (Dec 23 2019)2.4.5 (Feb 05 2020) > 2. > > Choose a package type: Pre-built for Apache Hadoop 2.7 Pre-built for > Apache Hadoop 3.2 and later Pre-built with user-provided Apache > Hadoop Source Code > 3. > > Download Spark: spark-3.0.0-preview2-bin-hadoop2.7.tgz > > <https://www.apache.org/dyn/closer.lua/spark/spark-3.0.0-preview2/spark-3.0.0-preview2-bin-hadoop2.7.tgz> > 4. > > Verify this release using the 3.0.0-preview2 signatures > > <https://downloads.apache.org/spark/spark-3.0.0-preview2/spark-3.0.0-preview2-bin-hadoop2.7.tgz.asc> > , checksums > > <https://downloads.apache.org/spark/spark-3.0.0-preview2/spark-3.0.0-preview2-bin-hadoop2.7.tgz.sha512> > and project release KEYS <https://www.apache.org/dist/spark/KEYS>. > > Note that, Spark is pre-built with Scala 2.11 except version 2.4.2, which > is pre-built with Scala 2.12. > > So, available binaries are based on scala 2.11 (not 2.12, 2.12 is used by > default in Spark 2.4.2, so probably documentation was updated while > releasing spark 2.4.2 but not roll backed. > > But the way I agree, it would be nice to have support for scala 2.12 if > there is no any blockers. > > Kind regards, > Denis > > On Thu, 21 May 2020 at 12:35, Pavel Martynov <mr.xk...@gmail.com> wrote: > >> Hi, folks! >> >> Looks like the last Spark release 2.4.5 completely dropped Scala 2.11 >> support.
