data resource has no table

Error message

%s data resource has no table

What it means

IllegalStateException from DataResource.getTable(): the resource's level is below TABLE (root, keyspace-only, or a non-table level resource), so it has no column family to return. The getter's contract requires a table-level resource; getKeyspace() has an analogous guard for the root resource.

Solutions

1. Call isTableLevel() before getTable() and handle non-table resources separately
2. Construct the resource at table level (datastores/keyspaces/tables) when a table name is required
3. Trace the caller (e.g. maybeCorrectResource) and skip or skip-level resources that are not table scoped

When it happens
