Hi all,
I'm writing M/R java program.
I want to abort a job itself in a map task, when the map task found
irregular data.
I have two idea to do so.
1. execulte "bin/hadoop -kill jobID" in map task, from slave machine.
2. raise an IOException to abort.
I want to know which is better way.
Or, whether there is better/recommended programming idiom.
If you have any experience about this, please share your case.

I'd go with throwing the exception. That way the cause of the job crash
will get displayed right in the Hadoop GUI.
