How to use Python kazoo library?
Question: I am planning to use Python kazoo library for Zookeeper. It's all about Python
question here not zookeeper at all I guess meaning how to use Python kazoo
properly..

I am totally new to python so I have no idea how to get going and how to use
kazoo to connect with zookeeper.

This is the document I was reading to start using kazoo for Zookeeper.

<http://kazoo.readthedocs.org/en/latest/install.html>

In that wiki, they have asked to install kazoo. And they are using some pip
command for that?

What does pip do here? And I am currently using windows so I have cygwin
installed and python installed as well. I am using Python 2.7.3

    
    
    host@D-SJC-00542612 ~
    $ python
    Python 2.7.3 (default, Dec 18 2012, 13:50:09)
    [GCC 4.5.3] on cygwin
    

Now what I did is - I copied this command exactly as it is from the above
website - `pip install kazoo` and ran it on my cygwin command prompt.

    
    
    host@D-SJC-00542612 ~
    $ pip install kazoo

Does it got installed properly? Now I can start writing code in python to
connect with zookeeper?

Sorry for asking all these dumb questions as I don't have any background with
python so learning little bit here..

It's all about Python question here not zookeeper at all I guess..


Answer: `pip` is common way to install packages. It queries and downloads the packages
from [pypi](https://pypi.python.org/pypi). Kazoo has been installed as per the
log statements. Give it a try.

you should be able to find the package at `where python is installed\lib\site-
packages\kazoo`.

You should try to load (import) the package without errors:

    
    
    from kazoo.client import KazooClient
    

After you have started the zookeeper. Your zookeeper configuration will have
the client port details.

    
    
    tickTime=2000
    dataDir=...../zookeeperdata/cluster/server1/data
    clientPort=2181
    initLimit=5
    

Use that to connect to zookeeper.

    
    
    # Create a client and start it
    zk = KazooClient(hosts='127.0.0.1:2181')
    zk.start()
    
    # Now you can do the regular zookepper API calls
    # Ensure some paths are created required by your application
    zk.ensure_path("/app/someservice") 
    
    # In the end, stop it
    zk.stop()
