Review request for Ambari, Dmytro Sen, Sumit Mohanty, and Sid Wagle.
Bugs: AMBARI-15063
https://issues.apache.org/jira/browse/AMBARI-15063
Repository: ambari
Description
-------
PROBLEM
Metrics Monitor failed to START at install on 1 host. Restart also never worked.
BUG
Ambari metrics monitor startup script had a stale pid file with value as 327,
and it used "ps ax -o pid | grep <pid>" to check if a monitor process is
already running. The above check always returned true since there was another
system process with process Id = 3327. Hence, the script assumed that the
metric monitor process was already running.
FIX
Change to use grep exact match (grep -w) while checking for process with
process ID.
