Hadoop fs查找块大小？ [英] Hadoop fs lookup for block size?

问题描述

在Hadoop fs中，如何查找特定文件的块大小？

我主要对命令行感兴趣，如：

  hadoop fs ... hdfs：//fs1.data / ... 
  

但它看起来不存在。是否有Java解决方案？

解决方案

似乎hadoop fs没有选项来执行此操作。 b

但是hadoop fsck可以。

您可以试试这个

  $ HADOOP_HOME / bin / hadoop fsck / path / to / file -files -blocks 
  

In Hadoop fs how to lookup the block size for a particular file?

I was primarily interested in a command line, something like:

hadoop fs ... hdfs://fs1.data/...

But it looks like that does not exist. Is there a Java solution?

解决方案

Seems hadoop fs doesn't have options to do this.

But hadoop fsck could.

You can try this

$HADOOP_HOME/bin/hadoop fsck /path/to/file -files -blocks
