anchor.diff:    name: <NAME OF YOUR CLUSTER>
   --------------------------------------------------
   
  -Make sure that you don't reuse the same cluster names in different
  -environments, otherwise you might end up with nodes joining the wrong cluster.
  -For instance you could use `logging-dev`, `logging-stage`, and `logging-prod`
  -for the development, staging, and production clusters.
  +请确保没有在不同的环境中复用相同的集群名称, 否则你可能会以节点加入到错误的集群而告终.
  +例如你可以使用 `logging-dev`, `logging-stage` 和 `logging-prod` 分别代表开发, 预发布以及生产环境集群.

   [[node-name]]
  -==== Node name
  -
  -You may also want to change the default node name for each node to
  -something like the display hostname. By default Elasticsearch will
  -randomly pick a Marvel character name from a list of around 3000 names
  -when your node starts up.
  +==== 节点名称
  +
  +您可能还想将每个节点的默认名称修改成显示的主机名. 当你启动节点的时候, Elasticsearch 默认会从近3000个名称列表中
  +随机地选取一个 Marvel 字符串名称.
   
   [source,yaml]

positive.code: }
  --------------------------------------------------
  
  Additionally, for settings that you do not wish to store in the configuration
  file, you can use the value `${prompt.text}` or `${prompt.secret}` and start
  Elasticsearch in the foreground. `${prompt.secret}` has echoing disabled so
  that the value entered will not be shown in your terminal; `${prompt.text}`
  will allow you to see the value as you type it in. For example:
  
  [source,yaml]
  --------------------------------------------------
  
negative.code: }
  --------------------------------------------------
  
  它也意味着很容易使用 `ES_JAVA_OPTS` 选项或作为 `elasticsearch` 命令的参数来提供外部的设置, 例如:
  
  [source,sh]
  --------------------------------------------------
  $ elasticsearch -Des.network.host=10.0.0.4
  --------------------------------------------------
  
  另一个选项是设置 `es.default.` 前缀而不是 `es.` 前缀, 它意味着仅当没有在配置文件中显示地设置时才使用默认设置.
  
  另一个选项是在配置文件中使用 `${...}` 符号, 这样会将其解析成一个环境变量设置, 例如:
  
  [source,js]
  --------------------------------------------------
