The shell script will disable some encryption algorithms.

What you can do is check the logs if the bash script gives any errors.

Also check if the /databricks/spark/dbconf/java/extra.security is actually there.

And also check the settings which are set in the script.

That's about it what I can think of. You could also try to use different versions of databricks, or check the databricks log, because maybe you have to disable/enable a certain algorithm which is not in the bash script.

Thinking out loud here though.
