I tested yesterday and it proves my theory. I'll share what I do under Windows
on 1 PC here with you experienced guys and further newbies:
1>Download zookeeper 3.4.8. I unzip it and copy to 3 other different folders:
zk_1, zk_2, zk_3.
2>For each zk_n folder, I do these things (Note: {n} means the last digit in
zk_n foler name):
a. Create zoo_data folder under root and create 'myid' with notepad,
the contents is pure '{n}' only.
b. Create zoo.cfg under conf folder with following contents:
clientPort=218{n}
initLimit=5
syncLimit=2
dataDir=D:/zk_{n}/zoo_data
;if p2p-coneect-port or leader-election-port are all same,
then we should set maxClientCnxns=n
;maxClientCnxns=3
;server.x=host:p2p-connect-port:leader-election-port
server.1=localhost:2888:3888
server.2=localhost:2889:3889
server.3=localhost:2890:3890
3> I download ZOOKEEPER-1122's zkServer.cmd. and go into each zk_n folder and
issue command:
bin\zkServer.cmd start
[Question]: There's something I'd like to ask guys: When I start zk_1,
zk_2, the console keeps shows some warning messages.
Only after I start zk_3, the warning messages is
stopped. Is that normal?
4> I use zkui_win to see them all go online successfully.
5> I goto Solr-5.4.1 folder, and issue following commands:
bin\solr start -c -s mynodes\node1 -z localhost:2181
bin\solr start -c -s mynodes\node1 -z localhost:2181 -p 7973
bin\solr create -c cugna -d myconfigsets\cugna -shards 1
-replicationFactor 2 -p 8983
6> By using zkui_win again, I see:
****** config 'cugna' are all synchronized on zk_1 to zk_3. So this
proves my theory, we only have to specify only one zk nodes and they'll sync
themselves. ******
[Question]: I go into zk_n folder and issue 'bin\zkServer stop'. However, this
shows error message. It seems it can't taskkill the zk process for some reason.
The only way I stop them
is by closing DOS windows that has issued the
'bin\zkServer start' command. Does anybody know why 'bin\zkServer stop' doesn't
work?
Note: Gotta say sorry for the repitition of localhost:2181. It's my typo.

Subject: Re: [scottchu] How to specify multiple zk nodes using solr
startcommand under Windows
The repetition is just a cut and paste from Scott's post.
How can I check if I am getting the ensemble or just a single zk?
Also if this is not the way to specify an ensemble, what is the right way?
Because the comma delimited list does not work, I concur with Scott.
