puppet 4.2 同步文件一个问题

[Hakmor]

在学习 puppet 4.2，写了一个 hello 模块，将 master 下的 /etc/puppetlabs/code/environments/production/modules/hello/files/hello.txt 下的文件同步在
agent 的 /tmp/hello.txt

报的错误是

Info: Retrieving pluginfacts
Info: Retrieving plugin
Info: Caching catalog for vm22796
Info: Applying configuration version '1438588739'
Error: /Stage[main]/Hello/File[hello]: Could not evaluate: Could not retrieve file metadata for puppet://modules/hello/hello.txt: getaddrinfo: Name or service not known
Notice: File has been created.
Notice: /Stage[main]/Hello/Notify[File has been created.]/message: defined 'message' as 'File has been created.'
Info: Class[Hello]: Unscheduling all events on Class[Hello]
Notice: Applied catalog in 2.08 seconds

我的代码是这样写的

class hello {

      file { 'hello':
      mode    => '0640',
      path    => '/tmp/hello.txt',
      source => "puppet://modules/hello/hello.txt",
    }

   notify { "File has been created." : }
}


class { 'hello' : }
