title: Why is mapreduce not Executed for Hive queries?
body: <p>I had one query where we have Hive table created and when we <code>select * from table  where=&lt; condition&gt;;</code> ,it gives results immediately without invoking MR job.When I create a same duplicate table and try to execute a query then MR is invoked. What could be the possible reason for this?</p>
