  <p>Is it possible to create an impala table to read the data from <code>/data/access/web1/*</code> directory (including sub directories)</p>
  
  <p>By default impala is not querying the data from sub directories.</p>
  
  <p>How to enable recursive reading in impala?</p>
  
  <p>Work around is to create a partition table in impala.
  But partition table doesn't fit our requirement.</p>
  
  <p>How to resolve this issue?</p>
