I was looking some more to confirm that the issue is between Cloudera Navigator host and Cloudera Manager host: 2015-04-15 23:20:50,677 WARN 236787520@scm-web-23643:org.mortbay.log: SSL renegotiate denied: java.nio.channels.SocketChannel[connected local=/{CM_SERVER_HOST}:7183 remote=/{NAVIGATOR_HOST}:50359] 2015-04-15 23:20:57,174 WARN 236787520@scm-web-23643:org.mortbay.log: javax.net.ssl.SSLException: Received fatal alert: certificate_unknown

After having succesfully enabled TLS encryption between Server and Agents, I am unable to load Cloudera Navigator UI. The log is pointing at issues with SSL handshake. I understand I need to configure SSL for Cloudera Navigator in addition to this, so I followed guidelines from Cloudera documentation: Open the Cloudera Manager Admin Console and navigate to the Cloudera Management Service. Click Configuration. Go to the Navigator Metadata Server Default Group > Advanced category, and add the following strings to the Navigator Metadata Server Advanced Configuration Snippet (Safety Valve) for cloudera-navigator.properties property. nav.http.enable_ssl=true nav.ssl.keyStore=<path to jks keystore with signed server certificate installed> nav.ssl.keyStorePassword=<password> Click Save Changes. Restart the Navigator Metadata server. After I added cloudera-navigator.properties to Safety Valve and restarted, Cloudera Management Services became unhealthy and I had to revert my change. I would like to clarify what values exactly go into nav.ssl.keyStore and nav.ssl.keyStorePassword. I have set nav.ssl.keyStore to same value as ssl.client.truststore.location, since this is where my keystore file lives. 2015-04-15 17:54:02,572 WARN com.cloudera.enterprise.EnterpriseService:

Got everything to work! Thanks all for useful tips. Uninstalled and did another clean install - this time ensured that Sentry server is installed on same node where Hue, Hive and Impala services are also installed. My FreeIPA user does not have sufficient privileges to create roles but I will fix that 🙂

Followed all steps outlined here http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/sg_sentry_service_config.html#concept_z5b_42s_p4_unique_1 (confuguring Sentry with Cloudera Manager) and Sentry is still not running.

I am going over all steps outlined here http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/sg_sentry_service_config.html 1. Permissions $ sudo -u hdfs hdfs dfs -chmod -R 771 /user/hive/warehouse
$ sudo -u hdfs hdfs dfs -chown -R hive:hive /user/hive/warehous 2. Disabled impersonation for HiveServer2 in the Cloudera Manager Admin Console 3. Set the Minimum User ID for Job Submission property to zero 4. Ensured the Allowed System Users property includes the hive user 5. Unchecked the Enable Sentry Authorization using Policy Files configuration property for both Hive and Impala under the Service-Wide > Policy File Based Sentry In the Service-Wide category for Hue/Hive/Impala, I will need to set the Sentry Service property to Sentry, but the option is not listed still. Going over all pre-req's again.

Added hostname to safety valve and restarted Hue service. Sentry service is definitely not running: # ps auxfww | grep sentry and # netstat -anp | grep 8038 ...return nothing, which explains my error in Hue. However, I was able to test HiveServer2 with beeline shell using above recommendation for the string. # beeline Beeline version 0.13.1-cdh5.3.0 by Apache Hive beeline> !connect jdbc:hive2://MY_FQDN_HOSTNAME:10000/default;principal=hive/MY_FQDN_HOSTNAME@MY_DOMAIN scan complete in 2ms Connecting to jdbc:hive2://MY_FQDN_HOSTNAME:10000/default;principal=hive/MY_FQDN_HOSTNAME@MY_DOMAIN Enter username for jdbc:hive2://MY_FQDN_HOSTNAME:10000/default;principal=hive/MY_FQDN_HOSTNAME@MY_DOMAIN: Enter password for jdbc:hive2://cjdbc:hive2://MY_FQDN_HOSTNAME:10000/default;principal=hive/MY_FQDN_HOSTNAME@MY_DOMAIN: Connected to: Apache Hive (version 0.13.1-cdh5.3.0) Driver: Hive JDBC (version 0.13.1-cdh5.3.0) Transaction isolation: TRANSACTION_REPEATABLE_READ 0: jdbc:hive2://MY_FQDN_HOSTNAME:10> show databases; +----------------+--+ | database_name | +----------------+--+ | default | | test | +----------------+--+ 2 rows selected (0.178 seconds)

I am going to troubleshoot HiveServer2 to make sure everything is running as expected there, as the error could point at some misconfigurations. I do think though that Cloudera Manager would have picked up if an issue with HiveServer2 was detected...
