Error while launching Kafka
<p>I have zookeeper daemons running on the relevant nodes and am trying to launch a kafka broker but getting the following error:</p>

<pre><code>FATAL [Kafka Server 13], Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)

<p>My server.properties</p>

<pre><code>broker.id=13
port=9092
host.name=node013
num.network.threads=3
num.io.threads=8
zookeeper.connect="node014:2181,node135:2181,node136:2181"
zookeeper.connection.timeout.ms=6000
</code></pre>

<p>and zookeeper.properties</p>

<pre><code>dataDir=/tmp/zookeeper
clientPort=2181
maxClientCnxns=0
</code></pre>

<p>I have tried but failed to figure out why the error logs are showing the extra " in the port property. Any idea what could be causing the issue ?</p>
