jps may not be available about exhibitor HOT 9 CLOSED

我也发现了这个问题。本来想今天提给你。 我觉着再加入第二步判断。jps没有的情况下。然后可以grep zoo.cfg
再查找一次。如果没有这是就基本可以判断，zk instance 进程是不存在的

Hey Jordan - I also noticed this error comes up when the server is already down and you try to restart it. This means it is trying to kill a server that is not up, fwiw.

@mdaumen - that should harmless, though, right?

Well yes but if you don't have jps you can't even start the server via exhibitor.

OK - I understand what you mean. Exhibitor blindly tries to kill ZooKeeper every time.

I haven't had a chance to get to this yet. I'll try to soon. Or, if you could, you could do it.

For real? I would be happy to.
