Hi,

Hadoop provides the Hadoop File system which is known as HDFS and its distributed file system. Hadoop files are distributed on the Hadoop clusters.

To upload a file you can use the following command:

 hadoop fs -put /<local machime path/filename> /<hdfs path/>

Above command will upload the file on Hadoop.

Following is the command to download the file:

 hadoop fs -get /<hdfs path> /<local machime path>

Thanks
