Error message "NoNode for /appconfig/hosts" when accessing Hosts page.

Did I miss any configuration?

gitorko commented 8 years ago

/appconfig/hosts - You will need to create a node under /appconfig for "hosts"

You need this only if you plan to use it in the host -> property path format. Which mean you have bunch of hosts host1.com points to /appconfig/path1 host2.com points to /appconfig/path2

For the error on monitor page, looks like the zookeeper server in config file is not correct.Its not able to run stat on the zk server. Check it with

$ echo stat|nc -q 2 localhost 2181 Zookeeper version: 3.3.5-1301095, built on 03/15/2012 19:48 GMT Clients: /127.0.0.1:620050
