> hadoop-daemon.sh script created pid files on when namenode, jobtrackers, etc. deamons
are started.
> When the deamon is stopped in a regular manner through the stop script, it should clean
up the pid file to indicate normal controlled exit.
> Presence of a pid without running corresponding process would then indicated abnormal
end of the process.
