First we have created a HDinsight Hadoop Cluster.

Then we created a table in Hive DB and import our big data.

then we have try to connect to HDinsight using Databrick notebook.

We also tried to execute script using ADF in hive but that also failed.

Hear are result for ADF script execution on hive DB.

@Vikrant Vikrant Thanks for sharing the details.

From the error message it looks like user configuration issue - Error 500, Internal Server Error can occur due to many reasons. Here are a few error sources.

Error occurs due to intermittent/transient issues.

Error occurred in the configuration of the webserver.

Error occurs due to permissions issues at client-server.

Error occurs due to time out.

If the issue is not resolved yet or you still experience the issue consistently, I would recommend raising a support ticket for the support engineer to investigate.
