Description

The sbin script pid detection is broken. Running star-dfs.sh indicates the following even if there are no processes are running and the pid dir is empty before starting.

hadoop-0.24.0-SNAPSHOT $ ./sbin/start-dfs.sh 
Starting namenodes on [localhost localhost]
localhost: starting namenode, logging to /home/eli/hadoop/dirs1/logs/eli/hadoop-eli-namenode-eli-thinkpad.out
localhost: namenode running as process 25256. Stop it first.

This may be in 23 as well.
