Hi, Zookeeper newbie here!
Just downloaded
http://www-us.apache.org/dist/zookeeper/zookeeper-3.5.2-alpha/zookeeper-3.5.2-alpha.tar.gz
and trying to make my first cluster. My intention is to deploy a single
server and add more instances to the ensemble. According to
https://zookeeper.apache.org/doc/trunk/zookeeperReconfig.html having a
static config file + dynamic + reconfig should be enough.
*This is my static zoo.cfg*
tickTime=2000
dataDir=/tmp/zookeeper
autopurge.purgeInterval=1
initLimit=5
syncLimit=2
maxClientCnxns=60
standaloneEnabled=false
dynamicConfigFile=/zk/conf/dynamic.conf
*And this is my server #1 dynamic.conf*
server.3 = 10.0.0.3:2181:2888;
IIUC, it doesn't matter what /id/ is (ie: it doesn't have to start with
1), but it should match /datadir myid/ file content.
This is what I got:
ZooKeeper JMX enabled by default
