6.11.4. Troubleshooting Cassandra Installations

  • Remember that changes to the DDL within the source database are not automatically replicated to Cassandra. Changes to the table definitions, additional tables, or additional databases, must all be updated manually within Cassandra.

  • If you get errors similar to:

    stage_xxx_access_log does not exist

    When loading into Cassandra, it means that the staging tables have not created correctly. Check the steps for creating the staging tables using ddlscan in Section 6.11.1, “Preparing Hosts for Cassandra Deployments”.
