title: Convert schema evolving (SCD) JSON/XML into ORC/Parquet format
body: <p>We are getting varieties of JSONs/XMLs as input where schema is always evolving. I want to process them using ORC or Parquet format in Hadoop/Hive environment for performance gain.</p>
  
  <p>I know below common style of achieving same objective :
  Use JSONSerde or XMLSerde library, first create hive table using these serde. Later select * fields query will be fired on each xml/json hive table to save as orc or save as parquet into another table. Once done successful I can drop these Serde Table and XML/JSON data.</p>
  
  <p>What would be another good ways of doing same ? </p>
