@Matt Clarke Thanks a lot for your time on this. Firstly, In nifi.properties file I did use below truststore: nifi.security.truststore=/opt/certs/truststore.jks I did create CA and all required certificates using openSSL and imported to truststore and I am using a single node here. I did import the CA certificate to browser but still I do see the same issue. Am I missing anything here? Also, I did not use any ldap-provider yet and this is my first step to verify https connection for NiFi. Could you advise me on this. ... View more

Thanks a lot for your patience on this and I really appreciate it from my end. I enabled logging . Everything seems good when HS2 is not integrated with AD. But, when I try to connect when HS2 is integrated with AD.. then I am not able to connect. Here is the log from Driver: Nov 19 08:05:53.526 ERROR 6096 DSTestResultDialog::Initialize: [DriverSupport] (1110) Unexpected response received from server. Please ensure the server host and port specified for the connection are correct and confirm if SSL should be enabled for the connection. Question: SSL is not enabled in the cluster and on the Tableau end or AD end or driver end, is it required?

Thanks a lot for your reply. Would like to get some technical explanation on the questions asked in CCA131. Whom should I contact? and I got a statement from Certification team which is like below:   "you must accept the questions that we ask you on the exam"    And I believe the questions should be valid as per the topics present in list of topics provided in CCA131 topics list and the weblink for the same is:   "https://www.cloudera.com/more/training/certification/cca-admin.html"   Unfortunately, I got a question from a topic listed in CCA Spark and Hadoop Developer topics and the topic list for the same is:   "https://www.cloudera.com/more/training/certification/cca-spark.html"   Do I need to accept the question yet and if it is yes then there will be no clarity on the topics for CCA131 and I believe CCA131 questions quality has to be improved from non-technical perspective.   I am wondering if I need to get ready for all certificaiton topics like Spark Developer Admin etc so that I can fit to the statement given by Cloudera -   "you must accept the questions that we ask you on the exam"  😞 😞     ...
