title: Copy parquet table between CDH clusters
body: <p>I need to copy parquet table from CDH4.5 to CDH4.3 cluster, to do so:</p>
  
  <ul>
  <li>used distcp to copy directory with data (/user/hive/warehouse/mytable)</li>
  <li>compared directory sizes</li>
  <li>fixed permissions and ownership to look the same on both clusters (777 and impala:hive)</li>
  <li>opened impala-shell and created the table</li>
  <li>invalidated metadata <code>invalidate metadata</code></li>
  <li>refreshed table <code>refresh mytable</code></li>
  </ul>
  
  <p>All good but impala doesn't see data. Impala restart doesn't help either. Is it possible to make it see copied data?</p>
