i have seen that the developers of zookeeper have a great zkServer.sh script to start,stop, restart etc zookeeper, but i have no idea why in the world they decided to skip init script to use.
With the zkServer.sh script no way to set zookeeper to run on startup of the server for example.
So anyone know how to wrap around or a usable and correctly working zookeeper init script?
here is link to the zkServer.sh file
Thanks for your help
Here is my example init script that i just need some help tunning

The problem now is if i do
service zookeerper start it never completes and if i go look at the running zookeeper services from another terminal session, i see like 3 of them..and when i do
service zookeeper status i get the following
