In Hadoop Distributed File System (HDFS), the mkdir command is used to create a new directory within the file system. This command allows you to organize and structure your data by creating directories to store files. Here’s how you can use the hadoop fs -mkdir command:

• <directory_path>: This is the HDFS path where you want to create the new directory.

For example, if you want to create a new directory named “mydata” in the root of HDFS, you can use the following command:

If you want to create a nested directory structure, you can specify the full path including subdirectories. For example:

In this example, the -mkdir command will create the “data” directory within the “hadoop” user’s home directory in HDFS.
