To access the Hadoop Web UI in Linux, you can follow the steps below:
- Start the Hadoop services by running the command start-all.sh in the Hadoop installation directory. This will start the Hadoop daemons, including the NameNode, DataNodes, ResourceManagers, and NodeManagers.
- Open a web browser on your Linux machine.
- In the web browser's address bar, enter the URL http://localhost:50070 to access the Hadoop NameNode Web UI. This UI provides information about the Hadoop cluster, including the overall cluster health, the number of live DataNodes, and the Hadoop file system.
- Alternatively, you can enter the URL http://localhost:8088 to access the Hadoop ResourceManager Web UI. This UI provides information about the cluster resources, running applications, and application logs.
Note: The default port numbers may vary depending on your Hadoop configuration. If you have customized the port numbers, replace the 50070
and 8088
in the URLs with your custom port numbers.
That's it! You should now be able to access the Hadoop Web UI in Linux.
