Hi All, I noticed recently in my dependency updates patch <https://gerrit.cloudera.org/#/c/7647/> that Spark 2.2.0 has dropped Java 7 support. This prompted me to think about dropping Java 7 support in Kudu as well. We may want to consider dropping Spark 1/Scala 2.10 support as well.
I have opened jiras to track each of these: - KUDU-2098 <https://issues.apache.org/jira/browse/KUDU-2098>: Drop Spark 1 Support - KUDU-2099 <https://issues.apache.org/jira/browse/KUDU-2099>: Drop Java 7 Support Note: These don't need to be resolved immediately but exist to track the discussion and target version in which we drop support. My questions to you all are: - Should/can we drop Spark 1 support in the next minor release? - Should/can we drop Java 7 support in the next minor release? Does it need to be a major release? - How should we support Spark 2.2.0 if we don't drop Java 7? Should we only require Java 1.8 for the Spark 2 modules? - Note: That will complicate the maven build and testing a bit. Once we have a plan, I am happy to put together patches or jira updates based on what we decide.
