title: Hive : Insert overwrite multiple partitions
body: <p>I have a Hive table partitioned on date. I want to be able to selectively overwrite the partitions for the last 'n' days (or custom list of partitions).</p>
  
  <p>Is there a way to do it without writing "INSERT OVERWRITE DIRECTORY" statement for each partition?</p>
  
  <p>Any help is greatly appreciated.</p>
