Hadoop mkdir

In Hadoop, you can create a new directory in the Hadoop Distributed File System (HDFS) using the hadoop fs -mkdir command. This command allows you to create a directory in a specified HDFS path.

The basic syntax of the hadoop fs -mkdir command is as follows:

• <hdfs-path>: This is the path in HDFS where you want to create a new directory.

Here’s how to use the hadoop fs -mkdir command to create a directory in HDFS:

1. Open a terminal or command prompt on a machine that has Hadoop installed and configured.

2. Use the hadoop fs -mkdir command to create a new directory in HDFS. Replace <hdfs-path> with the desired HDFS path for your new directory.

   bashCopy code

   hadoop fs -mkdir /user/username/new_directory
   • /user/username/: You can specify the HDFS directory where you want to create the new directory. Replace username with your Hadoop username or the desired path.

3. Press Enter to execute the command. Hadoop will create the specified directory in HDFS.

4. To verify that the directory was created, you can use the hadoop fs -ls command to list the contents of the parent directory:

   bashCopy code

   hadoop fs -ls /user/username/

   Replace /user/username/ with the appropriate HDFS path.
