Hadoop DFS ls

In Hadoop, you can list the contents of a directory in the Hadoop Distributed File System (HDFS) using the hadoop fs -ls command. This command provides information about files and directories within the specified HDFS path. Here’s the basic syntax:

• <HDFS_path>: The HDFS directory or file path you want to list.

To list the contents of the root directory in HDFS, you can use:

To list the contents of a specific directory, replace <HDFS_path> with the path to that directory. For example:

This command will display details about the files and subdirectories within /user/myuser/mydirectory. The output typically includes information such as file permissions, owner, group, file size, modification timestamp, and the file or directory name.

Keep in mind that you need the necessary permissions to list the contents of a directory in HDFS. If you encounter permission issues, you might need to use the hadoop fs -chmod command to adjust the permissions or contact your Hadoop cluster administrator for assistance.
