Cotizo sima commented on KAFKA-1817:
------------------------------------

I can reproduce the same error. Code:
{code}
	private static void tryCreateTopic(String zkConnString, String topicName) {
		final ZkClient zookeeper = new ZkClient(zkConnString);
		final int NR_PARTITIONS = 1;
		final int REPLICATION_FACTOR = 1;
		if (! AdminUtils.topicExists(zookeeper, topicName)) {
			LOG.warn(String.format("Topic %s not found, creating...", topicName));
			AdminUtils.createTopic(zookeeper, topicName, NR_PARTITIONS,
					REPLICATION_FACTOR, new Properties());
		} else {
			LOG.info(String.format("Topic %s found!", topicName));
		}
		zookeeper.close();
	}
{code}

>             Project: Kafka
>          Issue Type: Sub-task
>    Affects Versions: 0.8.2.0
>         Environment: debian linux current version  up to date
>            Reporter: Jason Kania
>             Fix For: 0.8.3

>
> When topics are created using AdminUtils.createTopic in code, no partitions folder is created The zookeeper shell shows this.
> ls /brokers/topics/foshizzle
> []
> However, when kafka-topics.sh --create is run, the partitions folder is created:
> ls /brokers/topics/foshizzle
> [partitions]
> The unfortunately useless error message "KeeperErrorCode = NoNode for /brokers/topics/periodicReading/partitions" makes it unclear what to do. When the topics are listed via kafka-topics.sh, they appear to have been created fine. It would be good if the exception was wrapped by Kafka to suggested looking in the zookeeper shell so a person didn't have to dig around to understand what the meaning of this path is...
