title: Trouble reading a parquet file into jupyter notebooks
body: <p>I uploaded a parquet file into amazon s3 from zeppelin and I'd like to download it into jupyter notebooks with python.</p>
  
  <p>Here's my upload code in scala</p>
  
  <pre><code>myFile.write.parquet("s3://company/myFile")
  </code></pre>
  
  <p>Here's my download code in python</p>
  
  <pre><code>import pandas
  import pyarrow.parquet as pq
  import s3fs
  s3 = s3fs.S3FileSystem()
  
  pandas_dataframe = pq.ParquetDataset('s3://company/myFile', filesystem=s3).read_pandas().to_pandas()
  pandas_dataframe.to_csv("myFile.csv")
  </code></pre>
  
  <p>It gives me back this error</p>
