Verifying Hadoop

Enter the URL in the address box of the browser to access the Hadoop web page. The URL format is http://server1:50070.

Change server1 to the IP address of the node where the server process resides. Check whether the number of live nodes is the same as the number of agent nodes (the quantity is 3 in this example) and whether the number of dead nodes is 0. If yes, the cluster is started properly.
