Description

This doc http://zookeeper.apache.org/doc/r3.1.2/zookeeperStarted.html ("Connecting to ZooKeeper" section) says:

Once ZooKeeper is running, you have several options for connection to it:

Java: Use
bin/zkCli.sh 127.0.0.1:2181

In fact, it doesn't work that way. I am running ZooKeeper with a different port to listen to client connections (2888), and this command

bin/zkCli.sh 127.0.0.1:2888

is still trying to connect to 2181.

output

PS1 I can connect to ZK at 2888 using ZK Java client from code specifying the correct port with no issues. But CLI seems just to ignore the provided host:port parameter.

PS2 Tried to run it with the pre-defined ZOOCFGDIR environment variable (to point to the path with the config file where the client port is set to 2888). No luck, same results as shown above.
