How can I list NameNode DataNodes from any machine in the Hadoop cluster

Question

How can I find the NameNode & DataNodes in a Hadoop cluster? Can anyone help me out with this?

Answer 1

You can use the jps command to check the daemons that are running in the cluster.

To know the report of your HDFS daemons, you can execute this command:

bin/hdfs dfsadmin -report

Answer 2

You can browse hadoop page from any machine in the cluster. For that you can use the below address.

http://NmaeNode IP:50070

Hope this will work.

Thank You
