zkConsole not returning results basis on my command
Techy Teck 2013-10-28, 20:13
I started my Zookeeper on my cygwin console like this and it got started
successfully -

    username@00542612 ~
    $ zkServer.sh start
    JMX enabled by default
    Using config: C:\ApacheZookeeper\zookeeper-3.4.5\conf\zoo.cfg
    Starting zookeeper ... STARTED

Now, after connecting to ZooKeeper. I opened a new Cygwin window, and issue
the following command

    $ zkCli.sh

which will connect to ZooKeeper server running at localhost:2181 by
default, and will open zk console. And this is what I got on the console.
And I believe till now everything is fine -
    username@00542612 ~
    $ zkCli.sh
    Connecting to localhost:2181

    WATCHER::

    WatchedEvent state:SyncConnected type:None path:null
    [zk: localhost:2181(CONNECTED) 0]
Now I was trying to do `ls /` to see how many nodes I have in general or I
also trying using help command and then press enter key but nothing is
happening on my console -

See below -

    WatchedEvent state:SyncConnected type:None path:null
    [zk: localhost:2181(CONNECTED) 0] ls /
After writing `ls /`  and I pressed enter, nothing showed up in my console
and same with `help` as well... This is my first time working with
Zookeeper.. Does anyone know what wrong I am doing here?
