Troubleshooting on YARN

General troubleshooting procedures to diagnose some of the commonly encountered issues in YARN.

Problem statement
The YARN UI does not display the Kill application button.
Root cause
Kerberos is not enabled.
Resolution
Enable Kerberos in order to view the Kill application button.
With the application state API, you can query the state of a submitted app as well as kill a running app by modifying the state of a running app using a PUT request with the state set to “KILLED”. To perform the PUT operation, authentication has to be set up for the Resource Manager (RM) web services.
