 Review comment:
   Jerry, thanks very much for your review and comment!
   It seems not work if setting it in hive-site.xml and putting hive-site.xml in Spark conf dir. I currently have no idea about the reason, but it seems have something to do with that SparkContext#hadoopConfiguration() does not take hive-site.xml into account, while it only cares the followings:
   - core-default.xml
   - core-site.xml
   - mapred-default.xml
   - mapred-site.xml
   - yarn-default.xml
   - yarn-site.xml
   - hdfs-default.xml
   - hdfs-site.xml
   
   if I get it correctly.
