Troubleshooting AWSE

This article discusses solutions to problems faced when using AWSE with Dremio.

Upgrading to 18.1.0

Problem: After upgrading to Dremio v18.1.0, when I access a table or view for my S3 source I receive the error: The preview engine is not online.

Solution: This issue is caused by a coincidence between a Zookeeper and Dremio port. To resolve this, first restart Zookeeper, and then restart the Dremio service.

note

If you continue to see this error with S3 sources, contact Dremio's Support Team.
