If you suspend a hadoop daemon with a kill -STOP $pid, the service hadoop-namenode stop operation will not actually terminate the process -it issues a kill -TERM "hint".
HADOOP-8353forces the shutdown with a sleep followed by a kill -9 if there is a process with that pid still listed. This forces the shutdown, and should have no adverse side effects provided that Pid doesn't get reused during the sleep phase.This JIRA covers backporting it to 1.1 and trunk
