Rahul Dhote updated HIVE-14796:
-------------------------------
    Description: 
During granting and revoking privileges on the table, OnGrant and OnRevoke 
method is required inside the MetastoreEventListener for capturing the events.
It would be useful for doing certain operation on this basic authorization 
events. 

Ex:

 /**
   * @param OnGrantEvent grant event
   * @throws MetaException
   */
  public void onGrant(GrantEvent grantEvent) throws MetaException {
  }

  /**
   * @param OnRevoke revoke event
   * @throws MetaException
   */
  public void onRevoke(RevokeEvent revokeEvent) throws MetaException {
  }

  was:
