Hello @mik-laj, how are you? Being a first-time contributor, can I ask you to approve running the workflows so that I can address any issues the PR checks raise? The change is a minor improvement to DatabricksSubmitRunOperator.

Also, cc-ing @potiuk, who has previously handled Databricks-related PRs. Thank you all!

Ci starting.

[gaborratky-db]

Hi @mik-laj, the CI checks seem to have failed on unrelated issues (docker: i/o timeout & breeze: command not found), would it be possible to run these checks again to arrive at a successful state? Thank you and have a great weekend!

[mik-laj]

Can you do a rebase?

Thanks for the suggestion, @mik-laj; the PR has passed all checks. Is there anything else I can do ahead of your code review?
