Hadoop Copy From Local to HDFS

To copy files or directories from your local file system to the Hadoop Distributed File System (HDFS), you can use the hadoop fs command with the -copyFromLocal option. This command allows you to upload files from your local machine to an HDFS directory. Here’s the basic syntax:

• <local-source>: Specifies the path to the file or directory on your local file system that you want to copy to HDFS.
• <hdfs-destination>: Specifies the destination directory in HDFS where you want to store the file or directory.

For example, if you want to copy a local file named example.txt from your local machine to the /user/hadoop/data/ directory in HDFS, you would use the following command:

Make sure that you have the necessary permissions to write to the specified destination directory in HDFS. If the destination directory doesn’t exist, the -copyFromLocal command will create it.

You can also copy entire directories from your local file system to HDFS by specifying the directory’s path as the <local-source>. For example:
