title: HIVE : External Table - how do you clean-up the files in loaded in the user/hive/warehouse/db/table directory
body: <p>According to the documentation, when we create an EXTERNAL table in HIVE, and then DROP the table, the metadata is updated and the data that was loaded in the HDFS directory /user/hive/warehouse//> still exists?</p>
  
  <p>I have two questions :
  1. How do you do clean-up of the files in the /user/hive/warehouse//>?
  2. When I tried to create the table again and the files are the same name but the data is different,  HIVE warehoouse files did not get updated 
  Should it be?? (I asked this since I am not sure if this is a set-up issue or an expected behavior) </p>
