Zayeem commented on KAFKA-778:
------------------------------
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'
