一个同步zookeeper节点的python脚本

#!/usr/bin/env python
#coding=utf-8

import logging
logging.basicConfig()

from kazoo.client import KazooClient
def diff_zk_child(src_host, dst_host):
    zk_src=KazooClient(hosts=src_host)
    zk_src.start()
    zk_dst=KazooClient(hosts=dst_host)
    zk_dst.start()
    zk_src_child=zk_src.get_children('/app_config/flume_agent/nodes')
    zk_dst_child=zk_dst.get_children('/app_config/flume_agent/nodes')
    #zk_src have but zk_dst not
    add_nodes=list(set(zk_src_child).difference(set(zk_dst_child)))
    delete_nodes=list(set(zk_dst_child).difference(set(zk_src_child)))
    print "add:"
    for node in add_nodes:
        print node
        if not zk_dst.exists('/app_config/flume_agent/nodes/'+str(node)):
            zk_dst.create('/app_config/flume_agent/nodes/'+str(node), b'node rsync')
    print "delete:"
    for node in delete_nodes:
        print node
        if zk_dst.exists('/app_config/flume_agent/nodes/'+str(node)):
            zk_dst.delete('/app_config/flume_agent/nodes/'+str(node))
    zk_src_child=zk_src.get_children('/app_config/flume_agent/nodes')
    zk_dst_child=zk_dst.get_children('/app_config/flume_agent/nodes')


if __name__ == "__main__":
    diff_zk_child('zk.prod.oa.com:2181', 'zk.mm.oa.com:2181')

这里没用zookeeper自带的python客户端，而是用的kazoo，没有依赖。
