title: Hive multiple users on same tables
body: <p>is that possible to have tables that are shared in hive.
  I mean a user creates a hive table. Later multiple users can work on that same table simultaneously.</p>
  
  <p>I heard about derby and individual metastore for each users. But individual metastore option does not allow users to work simultaneously on same set of tables right?</p>
  
  <p>Is there any other way to work on this?</p>
  
  <p>Because when we try to access hive at the same time, we get the following error-</p>
  
  <p>Caused by: ERROR XSDB6: Another instance of Derby may have already booted the da                                                                             tabase /root/metastore_db.</p>
