To put a file into a Hadoop Distributed File System (HDFS), you can use the `hadoop fs` command or the web interface provided by the Hadoop cluster.
Here is an example of using the `hadoop fs` command to put a file named `example.txt` into an HDFS directory called `/user/hadoop/input`:
```
hadoop fs -put example.txt /user/hadoop/input
```
This command will copy the file `example.txt` from the local file system to the HDFS directory `/user/hadoop/input`.
Alternatively, you can also use the web interface provided by the Hadoop cluster to upload a file to HDFS. Typically, you can access the web interface by navigating to the Namenode's web UI, which is usually located at `http://<namenode>:50070/`. From there, you can navigate to the desired directory and use the "Upload" button to select and upload a file.
