title: Python Error when I import CSV file into Cassandra workspace
body: <p>I'm using an Oracle database and I just started to use Cassandra. I started with a basic task like export/import CSV files. It works fine in my interaction env, but stall in production env. Here is the error:</p>
  
  <blockquote>
    <p>Process ImportProcess-1:Traceback (most recent call last):  File
    "/usr/lib64/python2.6/multiprocessing/process.py", line 232, ... ...
    Unable to connect to any servers', {'AQPLCS08': error('unpack requires
    a string argument of length 4</p>
  </blockquote>
  
  <p>I execute the import command like this:</p>
  
  <pre><code>cqlsh AQILCS01 -e "COPY ks_mdm.prueba_alarmas from '/tmp/datos_alarmas.csv'"
  </code></pre>
  
  <p>I look at the web for a workaround, but I didn't find any information.
  Does anyone know?</p>
