[jira] [Commented] (KAFKA-778) Fix unclear exceptions when the producer detects 0 partitions for a topic

["Zayeem (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-778?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13590244#comment-13590244 ] 

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'
	idPrefix = 'kafka'
}
