Hi
We have gone through the entire process of automating our cluster using blueprints and have had several successful deployments using wild cart certs in all our environments. We recently hit a snag in one of our larger environments where the ranger-admin though successfully installed with no errors whatsoever does not init the embedded tomcat server to listen on port 6182 when configured for ssl.
on a similar environment this is from the catalina.out on /var/log/ranger/admin

The environments are similar in setup and there is no difference. Tried to enable debugging by setting debug level for apache.ranger and spring.frameworks in log4j.xml and from ranger-admin-log4j.xml in the ui. Still there were no errors. Tomcat does not listen on port 6182 and the work directory under /usr/hdp/.../ranger/admin/ews/ ...doesnt have anything ?
Any suggestions on how to further debug this ? (apart from removing the service and re-installing)
from the xa_portal.log it looks like the spring application context gets initialized ..which is wierd .. all service install but can't connect to ranger on port 6182 because it is not listening on port 6182 !
