Description

watchdog_func at /src/main/python/ambari_agent/PackagesAnalyzer.py uses shell.killprocessgrp to kill subprocesses. This command is known to be not reliable (works not in all cases) , because not all subprocesses are in the same process group. That's why it ,may be better to replace it with shell.kill_process_with_children
