I wanted to follow up, because I'm not sure what the intention of the following code is:
https://github.com/douban/pymesos/blob/master/pymesos/detector.py

try:
    from zookeeper import ZooKeeperException as ZookeeperError
    from .zkpython import ZKClient, ChildrenWatch, DataWatch

    def adjust_zk_logging_level():
        pass
except ImportError:
    from kazoo.client import KazooClient as ZKClient
    from kazoo.recipe.watchers import ChildrenWatch, DataWatch
    from kazoo.exceptions import ZookeeperError

    def adjust_zk_logging_level():
        import logging
        import kazoo
        kazoo.client.log.setLevel(logging.WARNING)
        kazoo.protocol.connection.log.setLevel(logging.WARNING)

It looks to me like this code attempts to use the zkpython library, if available, and if not it falls back to kazoo.

kazoo is the pure python zookeeper client, which is preferable to me for the same reason that I'm attempting to use pymesos: it doesn't rely on native client libraries or installed headers.

I've been using kazoo, not zkpython, because I lack the zookeeper header files necessary to install zkpython. I would prefer to go the pure python route, since native libraries aren't available in my development environment (Mac OS X), or production (barebones Linux with no Internet access).

@dan-at-teza zkpython used in our production and we have no reason to replace it. You could either make it configurable(PR is welcome) or use your fork version.
