Hi *Does the Impala Ranger plugin support HTTPS when communicating with the Ranger Admin service?* - Yes
*If HTTPS is supported, is it one-way SSL or two-way (mutual) SSL?* - Both are supported. *If two-way SSL is required or supported, where should the Impala client certificate and truststore be configured on the Ranger Admin side?* - You can configure the certificate in the config - ranger.truststore.file and password for the truststore in the config - ranger.truststore.password. Both these configs are part of the ranger-admin-site.xml configuration file used by the Ranger Admin server. Also could you share more details about the message - 'Unauthorized access – unable to get client certificate' you are getting ? Where are you seeing this message ?
