hadoop-daemon.sh: tasktracker etc. does not stop on osx

[Marko Bauhardt <mb...@media-style.com>]

Hi all,
the stopping of namenodes or datanodes etc. does not work correctly  
on os x system.
e.g.
bin/hadoop-daemon.sh stop namenode
no namenode to stop

The reason is, the "/proc" directory does not exists on os x. The  
using of the "ps" command could be solve this problem. This command  
works on os x and linux etc.
Make that sense?
