How to create a directory in the root directory using Hadoop?

In Hadoop, you can create directories in the root directory using either the command line or the Hadoop API. Here, we will discuss both methods separately: 1. Command line method:

Open the terminal or command prompt, and navigate to the installation directory of Hadoop.

Execute the following command to create a directory:

    bin/hadoop fs -mkdir /your_directory_name

Replace `/your_directory_name` with the name of the directory you want to create. 2. Using the Hadoop API method:

Import the necessary Hadoop dependencies into a Java project.

– Use the following code to create a folder:

    import org.apache.hadoop.conf.Configuration;
     import org.apache.hadoop.fs.FileSystem;
     import org.apache.hadoop.fs.Path;
     
     public class CreateDirectory {
         public static void main(String[] args) throws Exception {
             Configuration conf = new Configuration();
             FileSystem fs = FileSystem.get(conf);
             Path directoryPath = new Path("/your_directory_name");
             fs.mkdirs(directoryPath);
             fs.close();
         }
     }

Replace `/your_directory_name` with the name of the directory you want to create.

Running the code will create a directory in the root directory. Whether you are using the command line or the Hadoop API method, make sure you have sufficient permissions to create a directory in the root directory before performing the operation.
