-------------------------------------
Summary: Ensure ulimit configs are honored
Key: AMBARI-15275
URL: https://issues.apache.org/jira/browse/AMBARI-15275
Project: Ambari
Issue Type: Bug
Affects Versions: 2.2.0
Reporter: Nick Dimiduk
I experienced a service outage today due to unconfigured ulimits. Ambari
installed configuration files into {{/etc/security/limits.d/}}, but presumably
because the machine had not been restarted, they are not having any effect.
This can be checked via {{cat /proc/$pid/limits}}. However, at installation
time, the sanity-check utilities give the green light.
Ambari should mention that a restart is required for some configuration changes
to take effect, and should notify operators that additional action is needed
when a cluster is not launching processes with the appropriate ulimits set.
