title: Hadoop Hive Data can't be seen in table / but present at hdfs location
body: <p>I created an External Table , specified it hdfs location.
  I use insert/overwrite query (insert into table tabley select * from tablex)
  data gets populated at hdfs location 
  but while I try to check values using
  select * from tabley</p>
  
  <p>I don't get any values.</p>
  
  <p>What could be the possible flaw ??</p>
