Ruby脚本在存储riak对象时挂起

我正在尝试执行《七周七个数据库》一书中的脚本hotel.rb。为了使它与riak 2.1.1兼容，我必须更改客户端的创建，除了它的脚本与可以从图书网站下载的脚本相同外：

require 'rubygems'
require 'riak'
STYLES = %w{single double queen king suite}
client = Riak::Client.new(:nodes => [
  {:host => 'localhost', :pb_port => 10017},
  {:host => 'localhost', :pb_port => 10027},
  {:host => 'localhost', :pb_port => 10037}
])

bucket = client.bucket('rooms')
# Create 100 floors to the building
for floor in 1..100
  current_rooms_block = floor * 100
  puts "Making rooms #{current_rooms_block} - #{current_rooms_block + 100}"
  # Put 100 rooms on each floor (huge hotel!)
  for room in 1...100
    # Create a unique room number as the key
    ro = Riak::RObject.new(bucket, (current_rooms_block + room))
    # Randomly grab a room style, and make up a capacity
    style = STYLES[rand(STYLES.length)]
    capacity = rand(8) + 1
    # Store the room information as a JSON value
    ro.content_type = "application/json"
    ro.data = {'style' => style, 'capacity' => capacity}
    puts "before storing"
    ro.store # Line 42
    puts "after storing"
  end
end

这是我得到的输出：

chris@desktop:~/Downloads$ ruby hotel.rb  
Making rooms 100 - 200 
before storing

在ro上调用store方法时，脚本似乎挂起。 这本书使用了riak版本1.0.2，我使用的是riak 2.1.1

更新：尝试使用Ruby 1.9.3和Ruby 2.0.0。我使用的是ubuntu 14.04

更新2：我使用了http端口而不是pb端口，现在在调用store时得到以下信息：

较新的客户端要求键名为字符串

ro = Riak::RObject.new(bucket, "#{current_rooms_block + room}")

---

仅供参考，这里有一个riak-client-2.2.1和ruby 1.9.3的工作示例

require 'rubygems'
require 'riak'
STYLES = %w{single double queen king suite}
client = Riak::Client.new(:nodes => [
 {:host => 'localhost', :http_port => 8098}
])

bucket = client.bucket('rooms')
# Create 100 floors to the building
for floor in 1..100
  current_rooms_block = floor * 100
  puts "Making rooms #{current_rooms_block} - #{current_rooms_block + 100}"
  # Put 100 rooms on each floor (huge hotel!)
  for room in 1...100
    # Create a unique room number as the key
    ro = Riak::RObject.new(bucket, "#{current_rooms_block + room}")
    # Randomly grab a room style, and make up a capacity
    style = STYLES[rand(STYLES.length)]
    capacity = rand(8) + 1
    # Store the room information as a JSON value
    ro.content_type = "application/json"
    ro.data = {'style' => style, 'capacity' => capacity}
    ro.store
 end
end

您是否尝试过将客户端中的节点一次减少到一个？也许其中一个端口有问题。您也可以尝试在pb_端口上转储数据包（ala tcpdump），可能服务器返回了一个客户端无法识别的错误。感谢您的提示，我使用了错误的端口。但是它仍然不起作用（参见更新2）。较新的客户端是否要求键名为字符串？这只是一个猜测，试试看：

ro=Riak:：RObject.new（bucket，“{current\u rooms\u block+room}”）

你说得对，非常感谢！如果你想写答案，我很乐意接受。我运气不好。尝试了ruby 1.9.3和ruby 2.0，在这两种情况下，riak-client-2.2.1表现相同（存储部分中的块），即使键名是字符串。明白了！由于riak ruby client 2.0.0发行版-2014-09-05

http支持已从riak ruby客户端中移除，转而关注协议缓冲区，因此我还不得不使用
：http\u port
而不是
：pb\u port
。
