Does this library currently work with spark 2.4?

We have not tried it with Spark 2.4 yet. On Wed, Feb 13, 2019 at 3:44 PM mattomatic notifications@github.com wrote:

It does not work with 2.3.2 as well

[icexelloss]

what issues do you see with 2.3.2? Internally we use flint with 2.3.2 without issues. On Fri, Feb 15, 2019 at 1:53 AM Sandro Cavallari notifications@github.com wrote:

I am running on spark-2.4.0-bin-hadoop2.7 and seeing the below error. Any idea ?

before this change what issue you were seeing ?

Is there any blockers to merging this in? I'd like to use Flint on Databricks but I don't see any compatible versions of Spark being offered (2.2.1 or 2.4.[0,1,2] are only versions of Spark currently available).

I think this is a great project and would love to help mature it!

I have been successfully using @mattomatic's changes to run on Spark 2.4.

@icexelloss Does this library work with spark 2.2.x version?
