Redshift configuration throws issue in Spark job

karthikj18 — Sat, 16 Nov 2024 04:00:36 GMT

Hi,

I'm getting the below while adding tRedshiftconfiguration component and submitting as Spark job.

Any resolution or work out ?

Hi,

The job is giving null pointer exception. Could you please double check whether all the values have been provided for Redshift and Spark Configuration?

Warm Regards,

Hi Nikhil,

Job running fine with the current Spark configuration, getting the below issue only while adding the tRedshiftConfiguration component. All the Redshift parameters are passed, non is passed empty or null values in connection parameters.

Hi,

I am not able to identify the error from current error message. I would recommend you to create a support ticket so that they can remotely check possible root cause using screen sharing session.
