Kafka to zookeeper command produces error
bin/kafka-topics.sh --create --topic activityTopic --zookeeper localhost:2181/kafka --partitions 1 --replication-factor 1
The above command from kafka produces an error
Error while executing topic command org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode for /brokers/ids

Any idea?
In my case, the problem was that I was specifying a non-existent kafka chroot.
I discovered that our company ops team had configured the kafka chroot as purple-elephants , and configured the creation of this chroot to be ensured on kafka service restart.
First I issued a sudo service kafka restart and the log shows that the chroot was created:
Ensuring chroot '/purple-elephants' exists
Starting Kafka server.
Then I simply issued:
bin/kafka-topics.sh --create --topic activityTopic --zookeeper localhost:2181/purple-elephants --partitions 1 --replication-factor 1
Try removing /kafka as the command is
bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 3 --topic Falcon
If it still occurs then be sure about the path in zookeeper.properties of
dataDir(default is /tmp/zookeeper)
and path in server.properties of
log.dirs(default is /tmp/kafka-logs)
while creating topic, it should be zookeeper url with --zookeeper option. It should work the following line if zookeeper & kafka are working.
--zookeeper localhost:2181
This link describes how to create a topic. You can also check the no of available ids in zookeeper cli. ./zkCli.sh & then ls /brokers/ids . At lease one broker id should be displayed.
