By default, the elastic_<s, m, or l> runnable (Elasticsearch) uses generic user credentials required for communication with other ARIS runnables. You can check and change the user name and the password if required.
Procedure
reconfigure elastic_<s, m, or l> +ELASTICSEARCH.aris.api.user.name="<new user name" +ELASTICSEARCH.aris.api.user.password="<new password>"
for example:
reconfigure elastic_m +ELASTICSEARCH.aris.api.user.name="administrator" +ELASTICSEARCH.aris.api.user.password="Thssmynwpsswrd"
stop ecp_m
You have changed the user credentials required for the Elasticsearch.
