title: Spark BigQuery Connector, set EU location
body: <p>I have been using the BQ connector that Google provides and contributing to another connector that abstracts the logic away</p>
  
  <p>my question is how can I write to an EU location via the spark API using the <code>saveAsNewAPIHadoopDataset</code>? </p>
  
  <p>Setting the location via the hadoop conf isnt enough it seems</p>
