Question

我知道有一个熟悉的标题问题，但我们要求的是不同的。我试过这个

hduser@tong-VirtualBox:/usr/local/hadoop$ bin/hadoop dfs -copyFromLocal /tmp/Text /home/hduser/Text

我明白了：

DEPRECATED: Use of this script to execute hdfs command is deprecated.
Instead use the hdfs command for it.

15/10/14 10:15:21 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
copyFromLocal: `/home/hduser/Text': No such file or directory

但是，我确实有/ home / hduser / Text我正在使用hdfs命令错误是什么意思？我该如何解决呢？

Answer 1

但是，我确实有/ home / hduser / Text而且我正在使用hdfs命令错误是什么意思？我该如何解决呢？

/ home / hduser / Text不存在或语法不正确。对于以后的情况，请尝试以下：

<强> hduser@tong-VirtualBox:/usr/local/hadoop$ bin/hadoop dfs -copyFromLocal /home/hduser/Text /tmp/Text

 To get rid of warning - DEPRECATED: Use of this script to execute hdfs command is deprecated. Instead use the hdfs command for it.

<强> hduser@tong-VirtualBox:/usr/local/hadoop$ hdfs dfs -copyFromLocal /home/hduser/Text /tmp/Text

copyFromLocal:

Usage: hdfs dfs -copyFromLocal <localsrc> URI

Similar to put command, except that the source is restricted to a local file reference.

Options:

    The -f option will overwrite the destination if it already exists.

将文件从本地复制到HDFS
