title: Error trying to start zookeeper server- Confluent setup
body: <p>I am trying to setup Confluent-4.1.1 on Ubuntu 16.04. To start the ZooKeeper server, I ran <code>./bin/zookeeper-server-start ./etc/kafka/zookeeper.properties.txt</code> from the root directory of Confluent by following this <a href="http://cloudurable.com/blog/kafka-tutorial-kafka-from-command-line/index.html" rel="nofollow noreferrer">tutorial</a>.<br>
