title: Changing bucket class(Regional/Multi Regional) in Google Cloud Storage connector in Spark
body: <p>Currently I am running my Dataproc cluster in region europe.
  I am running spark application on same cluster. While writing to bucket using Google cloud storage connector in spark, buckets are automatically getting created with Multi-Regional class and with Multiple Regions in US properties. </p>
  
  <p>I am writing file using </p>
  
  <pre><code>dataframe.write("gs://location").mode()...
  </code></pre>
  
  <p>This will create new bucket into location with properties mentioned above.</p>
  
  <p>Tried to find configuration to set storage class in connector but no success. How we can resolve this.</p>
