ezhux opened a new pull request #1109: [HUDI-238] - Migrating to Scala 2.12 URL: https://github.com/apache/incubator-hudi/pull/1109 Summary: - Migrating to Scala 2.12 - Migrating to spark-streaming-kafka-0-10 - Adapting Kafka and Zookeeper This includes some changes that are in https://github.com/apache/incubator-hudi/pull/1005 as well, but that PR is not merged yet. The main goal of this PR is to migrate to Scala 2.12. Along the way I had to upgrade the spark-streaming-kafka version from 0.8 to 0.10, because there is no spark-streaming-kafka-0.8 version for Scala 2.12. spark-streaming-kafka-0.10 uses Kafka 2.0 with the new Consumer API. In order to test it, I had to adapt some test classes from Spark core. Unit and integration tests do pass, but I haven't checked what has to be done in order to test with Docker. This if my first PR, so feel free to correct and advise. ## *Tips* - *Thank you very much for contributing to Apache Hudi.* - *Please review https://hudi.apache.org/contributing.html before opening a pull request.* ## What is the purpose of the pull request *(For example: This pull request adds quick-start document.)* ## Brief change log *(for example:)* - *Modify AnnotationLocation checkstyle rule in checkstyle.xml* ## Verify this pull request *(Please pick either of the following options)* This pull request is a trivial rework / code cleanup without any test coverage. *(or)* This pull request is already covered by existing tests, such as *(please describe tests)*.
