Hello

I add a new server Zookeeper as observer, but I am not sure if it's work
well or not, how can I test if the observer send OBSERVERINFO and don't
vote.

You can use the 4-letter command 'mntr', documented on the Admin's Guide: http://zookeeper.apache.org/doc/r3.4.8/zookeeperAdmin.html#sc_zkCommands

On the host running the node, run:
echo mntr | nc localhost 2181 #or whatever your configured client port is.

And check the zk_server_state entry.  It should say 'observer'.

Hi

Thank you for your help, 

I lookup for a scenario like request hive or any other scenario to improve
that the observer is called and used, because i am testing this in a small
cluster not in prod, so i need to initiate a test.

Regards
Rabii

Hi, look at that server’s log - it should say that it is observing.
