'kill' isn't very deadly
I have a script that executes 'kill' on an instance when needed. However,
the process isn't dying. After the "kill", ps still shows the process
running. Any ideas?

I guess that this counts as "disabled by default" with the additional
proviso that it can't be enabled at all.

the "kill" 4letterword was removed some time back (3.2.0) due to it
being a security issue:
https://issues.apache.org/jira/browse/ZOOKEEPER-346
It's no longer a supported word, see the docs (or lack thereof in this case):
http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_zkCommands

I believe (but should check) that the kill command is disabled by default.

I'm referring to the four-letter-word "kill". It's documented as saying it
stops the instance.

you might also look at bin/zkServer.sh, either to drive things or as
an example of how to start/stop.

kill -9
Review the man page to understand how a process responds to the different signals.
