Thanks. I checked the current setup with the LIVYSERVER service and it works fine. Now, I updated the ranger-knox-plugin module and want to copy the generated jar file in the server. I have two questions: 1. Is that ok to copy the jar file to the following directories?
/usr/hdp/current/knox-server/ext/ranger-knox-plugin-impl /usr/hdp/current/ranger-admin/ews/webapp/WEB-INF/classes/ranger-plugins/knox 2. Is it required to also copy other jar files such as ranger-plugins-common, ranger-plugins-audit to the server?
