title: How does one convert an HDF5 file into a Parquet file?
body: <p>I have stored approximately 800 GB of a huge dataframe into HDF5 via pandas with <code>pandas.HDFStore()</code>. </p>
  
  <pre><code>import pandas as pd
  store = pd.HDFStore('store.h5')
  df = pd.Dataframe() # imagine the data being munged into a dataframe
  store['df'] = df
  </code></pre>
  
  <p>I would like to query this with Impala. Is there a straightforward way to parse this data into Parquet? Or does Impala allow you to work with HDF5 directly? Is there another option for data on HDF5?  </p>
