title: Is Hadoop in Docker container faster/worth it?
body: <p>I have a <code>Hadoop</code> based environment. I use <code>Flume</code>, <code>Hue</code> and <code>Cassandra</code> in this system. There is a big hype around <code>Docker</code> nowadays, so would like to examine, what are pros and cons in dockerization in this case. I think it should be much more portable, but it can be set using <code>Cloudera Manager</code> with a few clicks. Is it maybe faster or why is worth it? What are advantages?
  Maybe should be only multi node <code>Cassandra</code> cluster dockerized?</p>
