Eli Collins commented on MAPREDUCE-1085:
----------------------------------------

What branch do you see this code in?  I don't see the code you're referring to on trunk or 21.  There's only one caller of getVMSetupCmd and it's fine with the null return value.

> For tasks, "ulimit -v -1" is being run when user doesn't specify mapred.child.ulimit.  Taking -1 as default value and using it in building the command is not right.
