nielm opened a new issue, #34600: URL: https://github.com/apache/beam/issues/34600
### What happened? When setting up a SpannerIO source/sink, if the [host](https://beam.apache.org/releases/javadoc/current/org/apache/beam/sdk/io/gcp/spanner/SpannerConfig.html#withHost-org.apache.beam.sdk.options.ValueProvider-) is set to either `null` string, a null ValueProvider, or a ValueProvider with a null or empty value, then the default host batch-spanner.googleapis.com is _not_ used, and the default host from the Spanner API libraries is used (or in the case of `null`, in recent spanner library versions, it fails). The default batch-spanner.googleapis.com should be used when an empty or null host value, or null valueprovider is specified . ### Issue Priority Priority: 2 (default / most bugs should be filed as P2) ### Issue Components - [ ] Component: Python SDK - [ ] Component: Java SDK - [ ] Component: Go SDK - [ ] Component: Typescript SDK - [ ] 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.
