Has anyone else observed setMaxMapAttempts() not having any effect?  I'm still seeing four attempts per mapper task.

I checked cdh3b2.

It should work.
What hadoop version are you using ?

This still isn't working for me.  My line is simply:

conf.setMaxMapAttempts(1);

I'm using 0.20.1+152 at the moment.  Admittedly, I need to upgrade, but still, shouldn't this work?
