How can Hadoop move files to the root directory?

In Hadoop, you can move files to the root directory using the following command:

hadoop fs -mv /path/to/source/file /destination/file

The path to the source file is the location of the file to be moved, and the path to the destination file is the location where it will be moved to. To move the file to the root directory, you can use / as the destination path.

For example, you can use the following command to move the file /user/hadoop/input/file.txt to the root directory:

hadoop fs -mv /user/hadoop/input/file.txt /file.txt

This will move the file file.txt to the root directory.
