        This is on 0.8 version.

        In the test code, I am trying to check if the topic exists, if so , create producer and send a message. In the zookeeper shell, i can see that the topic exists under /brokers/topics/<topicName>. However the listing /brokers/topics/<topicName> returns []

        Here is the gradle dependency versions of my project

        ext

        { junitVersion = '4.10' log4jVersion = '1.2.15' mockitoVersion = '1.9.0' springVersion = '3.1.3.RELEASE' springIntegrationVersion = '2.2.0.RELEASE' slfVersion = '1.6.4' commonsPoolVersion = '1.6' zooKeeperVersion = '3.3.4' snappyVersion = '1.0.4.1' scalaVersion = '2.9.2' idPrefix = 'kafka' }
