Dear all, In Sedona 1.0, we definitely will support Spark 3.0. But I wonder whether we should support Spark 2.4.
In order to support Spark 2.4, we need to do the following 1. Compile the source using Scala 2.11. Sedona master branch currently is compiled by Scala 2.12 and Java 1.8 2. For the Scala code of Sedona-SQL and Viz-SQL, I need to change the (1) UDF registration hook (2) the SQL aggregation function format 3. In the future releases of Sedona, use git cherry-pick to pick important features back to the Spark 2.4 branch. This is what I did in GeoSpark to support Spark 2.1, 2.2, 2.3 GeoSpark 1.2.0 - 1.3.1 support Spark 2.4 already. We can simply leave it that way and just support Spark 3.0. Do you think we should support Spark 2.4 in the future release? Thanks, Jia Yu
