ruby zookeeper

ruby 공부차, ruby에서 zookeeper 클라이언트(https://github.com/zk-ruby/zookeeper)를 사용한 예시이다. 

require 'json'

require 'zookeeper'

@zookeeper = Zookeeper.new("zk1.plus.google.com:2181")

@root_key = "redis"

@zookeeper.get_children(:path => @root_key).tap do |node|

  queue = node[:children]

  while ! queue.empty? do

    children_path = queue.shift

    child_node = @zookeeper.get_children(:path => @root_key + "/" + children_path)

    children_queue = child_node[:children]

    ........

    

  end

end
