Michael Bieniosek commented on HADOOP-1484:
-------------------------------------------

I'm not too worried about authentication/authorization.

There isn't really any authorization for the jobtracker itself right now, so 
anybody who can look at the web service can just run bin/hadoop job -kill from 
a command line (I guess one could write a firewall rule or turn off the web 
ui).  

Setting up an authentication system that can plug in with the diverse corporate 
authentication systems might be tricky.

> Killing job's is only possible through command line. We need killing job from 
> the web interface. Ideally all the actions that can be done using command 
> line tools should be available in the web interface
