Subject Re: java.lang.NullPointerException on some commands (stats, conf)
Date Wed, 01 Jan 2020 10:22:23 GMT
Hi Mike,

the ruok command is used to find out if the server is running or not. In
this case, no specific response is needed, the json you get is the expected
outcome both in secure and in unsecure mode. The idea is that you can poll
this url and as long as you get back a 200 OK HTTP status response, you can
see that the given ZooKeeper server process is up.

(this interface was mapped from the the ruok telnet command which also only
responses with a hardcoded "imok" text all the time)

Kind regards,
Mate
