I tried running the Ballista integration tests from the master branch and from #1253 and I get the following error.

Hi @andygrove, after datafusion used edition 2021, I also encounter similar error information. So I think you can try to upgrade the rust version.

Thanks @xudong963. The Rust version is defined in the Dockerfile in the repo. I will create a PR to update it.
