I usually apply these settings on my secondary browser.
Old Firefox versions:
Edit > Preferences > Advanced Connections > Settings>

New Firefox versions:
Goto: Edit > Preferences > General Settings > Network Proxy >

Ssh to any box in cluster to any local port:
ssh -D 9999 -i </path/to/ssh-key.pem> hadoop@<ip address of master node>
Visit application on browser :
http://<master ip address>:8088/cluster/apps/RUNNING. // With Destination IP and destination port.
Hope this crips post is useful. Cheers.
