The implementation backing the column (the plain ValuesReader path, and the dictionary-backed variant) does not support reading timestamps, so calling readTimestamp()/readTimestamp(int id) on this reader is an unsupported-operation contract violation by the caller: the readVector layer invoked a timestamp read for a column whose physical Parquet type or reader factory variant cannot decode it. The faulting input is a readTimestamp call against this non-timestamp reader instance; the error carries no cause and simply fails fast instead of returning garbage.","triggerScenarios":"Triggered at runtime when the operation fails because: Unsupported operation.","commonSituations":"Commonly caused by misconfiguration, missing dependencies or files, unsupported types or operations, or invalid user input leading to: Unsupported operation.","solutions":["Address the cause reported by the error message: Unsupported operation","Verify the inputs, configuration values, and classpath/dependency setup related to this operation, then retry."],"exampleFix":"Correct the condition described (\"Unsupported operation\") and rerun the job or command.","handlingStrategy":"type-guard","validationCode":null,"typeGuard":null,"tryCatchPattern":null,"preventionTips":[],"tags":[],"backgroundTag":null,"analyzedSha":"2f3c205e9266cb30240eb7f4fdab15cad629a70f","analyzedAt":"2026-08-14T08:48:24.518Z","contentChangedAt":"2026-08-14T08:48:24.518Z","schemaVersion":2},"datasetVersion":"2026-09-23T08:17:48.524Z"}
