Subject Re: Prevent users from killing each other's jobs

You need to set up Job ACLs. See http://hadoop.apache.org/docs/stable/mapred_tutorial.html#Job+Authorization.

It is a per job configuration, you can provide with defaults. If the job owner wishes to give
others access, he/she can do so.

Thanks,
