             Summary: Allow writing to time partitioned tables when 
CreateDisposition==CREATE_NEVER
                 Key: BEAM-4685
                 URL: https://issues.apache.org/jira/browse/BEAM-4685
             Project: Beam
          Issue Type: Improvement
          Components: io-java-gcp
            Reporter: Chamikara Jayalath


Writing to time partitioned table fails when CreateDisposition==CREATE_NEVER 
with error "Table with field based partitioning must have a schema".

This seems to be due to BigQuery not setting schema for this case.
