-----------------------------------

             Summary: [BigqueryIO] MoreObjects.firstNonNull should not be called with null
                 Key: BEAM-14299
                 URL: https://issues.apache.org/jira/browse/BEAM-14299
             Project: Beam
          Issue Type: Bug
          Components: io-java-gcp
            Reporter: Buqian Zheng
            Assignee: Buqian Zheng


[https://github.com/apache/beam/blob/2e0f79ef2b924da3306d0e55dffd4728809b9f3d/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/bigquery/StorageApiWritesShardedRecords.java#L516] if streamName.read() returns null, [firstNonNull|https://guava.dev/releases/20.0/api/docs/com/google/common/base/MoreObjects.html#firstNonNull-T-T-] will throw NullPointerException. We check the nullness in the next line so it's ok for stream to be null, we should assign streamName.read() to stream directly.
