Hi @yc000000,

I saw your new thread [here](https://discuss.hail.is/t/failed-to-use-hail-on-cloud-aws/2226), but let’s keep it all in one thread.

It’s difficult for us to diagnose what is going wrong without more of the error output. Was there more printed that you could share, possibly using pastebin if it’s too long? If not, you could try running gradle with the `--stacktrace` option.

Also, is there a reason you’re unable to use Scala 2.12? We test with Scala 2.12 and Spark 3.1.1.
