> This is with latest master, which has elasticsearch 5.6.2.
> On a Centos 7, it is seen that the Elasticsearch service fails to start with error as follows:
> {code}
> [2017-12-07T10:06:36,451][ERROR][o.e.b.Bootstrap ] [metron-1.openstacklocal] node validation exception
> [1] bootstrap checks failed
> [1]: memory locking requested for elasticsearch process but memory is not locked

> {code}
> There was no change in behavior after adding the entry "MAX_LOCKED_MEMORY=unlimited" in /etc/sysconfig/elasticsearch.
> I found that ES 5.x requires additional configuration for environments that use systemd (like CentOS 7). The following link explains the changes required:
> https://www.elastic.co/guide/en/elasticsearch/reference/master/setting-system-settings.html#systemd
> This hence needs to be done at install/configuration time for ES to come up properly on OS' that use 'systemd'.
