How to access to HDFS namenode UI

Question

Hello,
I have an HdInight cluster, but I can't access to the HDFS namenode UI.
In Ambari, the link to access HDFS namenode UI is: https://{CLUSTERNAME}/da/host/hn0-testlo.nmfkjwercu3efldgcwsgpmaqge.ax.internal.cloudapp.net/port/30070/
But, when I access this endpoint, I receive the error 404- Not found.
Without HDFS UI I can't upload/download/visualize files and directories just by SSH connection.

Hello @Paulo Barbosa ,

Thanks for the question and using MS Q&A platform.

HDInsight clusters provide access to the Apache Ambari web UI over the Internet. Some features require an SSH tunnel. For example, the NameNode web UI can't be accessed over the internet without an SSH tunnel.

Several of the menus in Ambari only work through an SSH tunnel. These menus rely on web sites and services running on other node types, such as worker nodes.

The following Web UIs require an SSH tunnel:

• JobHistory
• NameNode
• Thread Stacks
• Oozie web UI
• HBase Master and Logs UI

After following the below document, I'm able to access the HDFS NameNode UI without any issue.

For more details, refer to Use SSH tunneling to access Apache Ambari web UI, JobHistory, NameNode, Apache Oozie, and other UIs.

Hope this will help. Please let us know if any further queries.
