> 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 {
>   }
