title: Where is the error log file destination for Zookeeper distributed with Kafka?
body: <p>I'm a bit confused on how to configure where the error log files are written for Zookeeper when running ZK and Kafka on the same node.  I understand it uses log4j and there is a zookeeper.properties file.  I assume it is using some sort of default out of the box.  If I do:</p>
  
  <pre><code>sudo lsof -p 31311 | grep log | grep zoo
  </code></pre>
  
  <p>I get:</p>
  
  <pre><code>java    31311 root    1w      REG              259,1     24962  134739 /home/ec2-user/zookeeper-start-log
  java    31311 root    2w      REG              259,1     24962  134739 /home/ec2-user/zookeeper-start-log
  java    31311 root    3w      REG              259,1     22350 1050171 /opt/Kafka/kafka_2.11-1.1.0/logs/zookeeper-gc.log.0.current
  java    31311 root   94w      REG              259,1  67108880  394260 /var/local/zookeeper/data/version-2/log.1
  </code></pre>
  
  <p>If I want to explicitly specify my error log locations for zookeeper, what exactly do I specify in the zookeeper.properties file?</p>
