Allen Wittenauer commented on MAPREDUCE-220:
--------------------------------------------
(You know, it is a shame this was called ProcfsBasedProcessTree with the
disclaimer that it only works on Linux. It probably should be renamed
LinuxProcfsBasedProcessTree so that other operating systems with /proc could
work. I suppose the alternative is to hack this code to be multi-OS aware)
