Hi Matthew,
Re-writing srcript is a costly job. I've also run zookeeper as a
non-root user since last month. Everything still go fine up to now and here
are what I have done:
-Download zookeeper, up-pack it and upload to my server under
/home/zookeeper (home for zookeeper user)
-Configure zoo.cfg at each server, mostly change dataDir back to
some folder under /home/zookeeper
-Create a myid file under dataDir at each server
-Writing a bash script which first move to bin folder and then invoke
zkServer.sh start
-Log in to server using zookeeper account and run above script.
That's all.
Honestly, I don't have any need to automatically start zookeeper at
start-up time, so placing any script under /etc/init.d/ is not under my
consideration. Hope this will help you.
P/S: make sure all above files and folder belong to zookeeper, not root
user.
