我正在对 Hadoop 框架进行一些研究.我想问一下框架中可以使用的属性..例如

I'm making some research on the Hadoop framework. I would like to ask about the property that can be used in the framework.. For example

  • io.sort.mb
  • io.sort.record.percent

是否有任何参考可以让我了解这个框架的整个属性列表?非常希望有人可以帮助我.

另外,我想问一下,io.sort.mb 和 mapreduce.task.io.sort.mb 有什么区别吗?或者他们是一样的?

Is there any reference that I can can the whole properties list of this framework? Very hopefully that someone can help me.

Besides, I would like to ask if, is it any difference for io.sort.mb and mapreduce.task.io.sort.mb? Or they are just the same?

推荐答案

以下是按配置文件分类的配置属性的完整列表:

Here are complete list of configuration properties categorized by configuration files:

  • 进入 core- 的属性站点.xml
  • 进入 hdfs- 的属性站点.xml
  • 进入 mapred-site.xml
  • 进入 yarn- 的属性站点.xml

关于你的其他问题:

io.sort.mb 和 mapreduce.task.io.sort.mb 有什么区别吗?还是它们都一样?

is it any difference for io.sort.mb and mapreduce.task.io.sort.mb? Or they are just the same?

除了 io.sort.mb 已从 Hadoop 2.0 中弃用之外,其他内容相同.

There are the same, except that io.sort.mb is deprecated from Hadoop 2.0.
