Hi @DSoni,

By default hive_metastore uses an RDS in AWS, in the failure you can see: xyz.region.rds.amazonaws.com which I think you redacted, that is the host with the issue. I would require more details to check hive_metastore comes into picture if you mentioned no hive_metastore table is being used. 

Was the error observed during a workflow run? or during a manual query?
