Error message
Schema is not instanceof CatalogManagerSchema or BeamCalciteSchema
What it means
SET (pipeline option) operations require the schema to be a CatalogManagerSchema or BeamCalciteSchema so Beam can get/set/remove pipeline options. If execute() resolves any other schema type, it raises this internal error because pipeline options cannot be stored there.
Solutions
- Run SET against a Beam SQL connection backed by BeamCalciteSchema/CatalogManagerSchema
- Use the default Beam SQL environment (e.g. BeamSqlEnv or the standard SQL shell)
- Verify the schema the statement resolves to in your embedded setup
- Set pipeline options programmatically via PipelineOptions if SET is unavailable
Defensive patterns
Strategy: type-guard
Validate before calling
if (!(schema instanceof BeamCalciteSchema) && !(schema instanceof CatalogManagerSchema)) {
throw new IllegalStateException("SET pipeline options requires a Beam-managed schema");
} Type guard
boolean supportsPipelineOptions(Schema s) {
return s instanceof BeamCalciteSchema || s instanceof CatalogManagerSchema;
} Prevention
- Run SET/RESET pipeline-option statements only in standard Beam SQL sessions
- Set options via PipelineOptions API in embedded/custom setups
- Verify resolved schema type before issuing SET commands
When it happens
Trigger: `SET <option> = 'value'` (or SET '<option>' / RESET variants) in a session whose resolved schema is neither CatalogManagerSchema nor BeamCalciteSchema.
Common situations: Running Beam SET commands over a plain Calcite schema connection; embedding Beam SQL with custom root schemas; typos causing resolution to a non-Beam schema.
