title: Create or replace view hive
body: <p>What is the similar syntax for create or replace view(which exists in RDBMS) in hive.
  For example,
  Create or replace view as select * from table1.</p>
  
  <p>I know there is syntax <strong>create if not exists.</strong></p>
  
  <p>But in my case, view exists in lower environment, so i want to replace and view if doesn't in higher environment , i need to create. </p>
  
  <p>Since i need to do source-code once and deploy in all environments. I need similar code to create or replace view.</p>
  
  <p>Can someone please help?</p>
