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?
