Description

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.
