hichmo opened a new issue, #35777: URL: https://github.com/apache/beam/issues/35777
### What happened? #### **Description** When using the **BigQuery emulator** in combination with `BigQueryIO.read()` in **Apache Beam (Java)**, the pipeline fails with the following error when running locally with `DirectRunner`: ``` java.lang.IllegalArgumentException: BigQueryIO.Read needs a GCS temp location to store temp files. This can be set with option --tempLocation. ``` This makes it **impossible to write integration tests** against the emulator using `BigQueryIO.read()` unless a (fake) GCS-compatible path is provided—even though the emulator does not support or require real GCS interaction. #### **To Reproduce** Steps to reproduce the behavior: 1. Start BigQuery emulator (e.g., [[goccy/bigquery-emulator](https://github.com/goccy/bigquery-emulator)](https://github.com/goccy/bigquery-emulator)) 2. Create a Beam pipeline that reads using `BigQueryIO.readTableRows().from(...)` 3. Set `bigQueryEndpoint` to point to the emulator 4. Omit `tempLocation` (or use a local one) 5. Run with `DirectRunner` #### **Expected behavior** The pipeline should be able to run against the emulator. #### **Environment:** * Beam version: `2.63.0` (also affects earlier) * Runner: `DirectRunner` * Java SDK * Emulator: `ghcr.io/goccy/bigquery-emulator` ### Issue Priority Priority: 2 (default / most bugs should be filed as P2) ### Issue Components - [ ] Component: Python SDK - [x] Component: Java SDK - [ ] Component: Go SDK - [ ] Component: Typescript SDK - [x] Component: IO connector - [ ] Component: Beam YAML - [ ] Component: Beam examples - [ ] Component: Beam playground - [ ] Component: Beam katas - [ ] Component: Website - [ ] Component: Infrastructure - [ ] Component: Spark Runner - [ ] Component: Flink Runner - [ ] Component: Samza Runner - [ ] Component: Twister2 Runner - [ ] Component: Hazelcast Jet Runner - [ ] Component: Google Cloud Dataflow Runner -- This is an automated message from the Apache Git Service.
