How to kill the job using the Job Tracker web Interface.
update webinterface.private.actions in mapred-site.xml to true from false to all the nodes and restart the jobtracker.

true the web interfaces for the JobTracker gain some advanced options like killing a job(please see the screenshot below). It makes life a lot easier while still in development or evaluation. But you probably should set this to false once you rely on your Hadoop cluster for production use for security purpose.
