---------------------------------------
Resolution: Fixed
> Improve error handling in Databricks hook
> -----------------------------------------
>
> Key: AIRFLOW-2709
> URL: https://issues.apache.org/jira/browse/AIRFLOW-2709
> Project: Apache Airflow
> Issue Type: Improvement
> Components: contrib, hooks
> Reporter: Victor Jimenez
> Priority: Major
>
> The Databricks hook handles both connection and timeout errors. However,
> Databricks sometimes returns a temporarily unavailable error. That error is
> neither a connection nor timeout one. It is just an HTTPError containing the
> following text in the response: TEMPORARILY_UNAVAILABLE. The current error
> handling in the hook should be enhanced to support this error.
> Also, the Databricks hook contains retry logic. Yet, it does not support
> sleeping for some time between requests. This creates a problem in handling
> errors such as the TEMPORARILY_UNAVAILABLE one. This error typically resolves
> after a few seconds. Adding support for sleeping between retry attempts would
> really help to enhance the reliability of Databricks operations.
