在webhdfs中,length和spaceConsumed有什么区别?

In webhdfs, what is the difference between length and spaceConsumed?

使用webhdfs we can get the content summary of a directory/file.

但是,我不清楚以下属性:

"length":
        {
          "description": "The number of bytes used by the content.",
          "type"       : "integer",
          "required"   : true
        }


"spaceConsumed":
        {
          "description": "The disk space consumed by the content.",
          "type"       : "integer",
          "required"   : true
        }

它们之间到底有什么区别? spaceConsumed 磁盘复制的大小是否包括在内?内部 method documentation 未提供更多详细信息。

根据同事的说法,答案是:

spaceConsumed = length * replicationFactor

但是,我没有任何资料可以证明。
