Andrew Ferguson commented on MAPREDUCE-4334:
--------------------------------------------
Forgot to mention that this version requires the "cgexec" binary, which, while
not required for cgroups, is commonly available. If we choose not to introduce
a dependency on cgexec, then we can return to modifying the C code in
LinuxContainerExecutor, as the previous version of this patch did.
thanks,
Andrew
