Can't connect to zookeeper

[dlspring0315]

requirements Zookeeper 3.3.3, but I use kafka_2.9.2-0.8.1, and its zookeeper version is 3.3.4. Wile I register zookeeper, the status always is connecting...

Which version of the console are you using? What happens if you use Kafka 0.8.0?

[dlspring0315]

I use the newer one, it‘s kafka-web-console-master,

[cjmamo]

The master branch is the snapshot version so it isn't stable. Please install the latest release.

now, I change the version to console-1.1.0, and modify the conf log from info level to debug level.

Oh, Successful connection. when I register Zookeeper, fill the Chroot with /, then shows that ,cann't connect to the zookeeper. Now I fill a blank for Chroot , successful connection. So, What is the role of the Chroot ?

[cjmamo]

Zookeeper will interpret all commands relative to the chroot. If the field is empty then '/' is used.
