Description

Linux ps command output produces white space in front of the pid number, if the pid is lesser than 5 digits number. The current shell script does not parse this correctly for watchdog. In addition, CHUKWA_PID_DIR needs to be better supported by chukwa's shell script. In some of the shell scripts, the reference to pid file is in CHUKWA_HOME/var/run, and this should be changed to CHUKWA_PID_DIR.
