Hi @dszeto
My suggestion is based on #352. This is what I see moving forward.
- Define the versions of Scala to build against in the `crossScalaVersions`
setting.
- Iâd be happy if it would be possible to deprecate Spark 1. We keep
using the class (especially SQLContext) that keeping for backward compatibility
for a while.
- Or the code that depends on version of Spark makes it abstract, and
separate build. The jar that depends on Spark 1 is in lib/spark and the other
is in lib/extra. In order to use Spark 2, one would replaced like ES5.
Note that this is just my imagination for now. Thus, I would like to try
this out if this suggestion takes a turn for the better. For that, I think I
need to some more time. Do you have any thoughts?
