Re: Support Spark 2.4 in Sedona 1.0
Hi Jia, I think we should support spark 2.4, a lot of users still use it. More than that I think more users still have jobs written in spark 2.4 than 3.0. We will use an additional branch for that use case ? I mean Spark 2.4 with scala 2.12 is important one.

Re: Support Spark 2.4 in Sedona 1.0
Hi, I also think that we need to support 2.4. I saw that even Apache Spark still releases 2.4.x artifacts. (2.4.7 Sep 12, 2020) I also asked about it on us...@spark.apache.org : Sean Owen (answered the question): "I don't think there's an official EOL for Spark 2.4.x but would expect another maintenance release in the first half of 2021 at least.

Re: Support Spark 2.4 in Sedona 1.0
OK. I agree. I am gonna create a branch for spark-2.3/2.4. Regarding the compiler used in each branch, For Sedona on Spark 3.0, I will compile it using Scala 2.12 For Sedona on Spark 2.4, I will compile it using Scala 2.11. For the Java code in both branches, I will compile them using Java 1.8 Am I missing anything here?

Re: Support Spark 2.4 in Sedona 1.0
I am not sure it should be a branch? It is common to deal with this as a compile target, not as a separate branch. A separate branch might have difficulty to release? There are a few example in projects where they handle multiple Spark target version like this. On Wed, Nov 11, 2020 at 12:56 PM Jia Yu wrote: > OK. I agree.

Re: Support Spark 2.4 in Sedona 1.0
What do you mean by compile target? ?

Re: Support Spark 2.4 in Sedona 1.0
In order to support Spark 2.4, Sedona needs to use different logic for SQL aggregation functions. I am not sure if this could be achieved by using different profiles.
