							 Hi,   Getting these two errors when trying to install ranger,   Internal Exception: java.sql.SQLException: No database selected
Error Code: 1046   [E] applying java patch PatchPasswordEncryption_J10001 failed   When I googled regarding this,   ranger-admin-site.xml has bad/missing values for:   - ranger.externalurl   - ranger.jpa.audit.jdbc.url   - ranger.jpa.jdbc.url   Of which I have only one property configured in my blueprint(ranger.jpa.jdbc.url)
what should be the values of this..  
It was jdbc:mysql://ip_of_ranger_host   Then I changed it to jdbc:mysql://ip_of_ranger_host/ranger  Thanks in Advance!

							 Hi, I've been trying to add atlas 0.7 to ambari(2.4) cluster, the following configuration settings were asked to be filled in the customize service tab,   atlas.audit.hbase.zookeeper.quorum   atlas.graph.index.search.solr.zookeeper-url   atlas.graph.storage.hostname  I'm not sure what needs to be filled here..the services in the cluster includes   HDFS,YARN,MAPREDUCE,TEZ,HIVE,PIG,ZOOKEEPER,RANGER,SLIDER  in addition to that kafka was also required by atlas..  I'm getting an error saying "server error" when trying to add atlas, kafka and deploy the cluster.

							 Hi, I've upgraded ambari from 2.2 to 2.4. when ambari was started using "ambari-server start" got the error as follows,  DB configs consistency check failed. Run "ambari-server start --skip-database-check" to skip. If you use this "--skip-database-check" option, do not make any changes to your cluster topology or perform a cluster upgrade until you correct the database consistency issues. See "/var/log/ambari-server/ambari-server-check-database.log" for more details on the consistency issues. Ambari database consistency check finished  In /var/log/ambari-server/ambari-server-check-database.log 2016-12-20 00:33:28,188  INFO - ******************************* Check database started ******************************* 2016-12-20 00:33:47,630  INFO - Checking for configs not mapped to any cluster 2016-12-20 00:33:47,703  INFO - Checking for configs selected more than once 2016-12-20 00:33:47,762  INFO - Checking for hosts without state 2016-12-20 00:33:47,792  INFO - Checking host component states count equals host component desired states count 2016-12-20 00:33:47,826  INFO - Checking services and their configs 2016-12-20 00:34:00,127 ERROR - Required config(s): usersync-properties,ranger-site is(are) not available for service RANGER with service config version 3 in cluster atlas   So instead started ambari using "ambari-server start --skip-database-check" and the it worked fine. In /var/log/ambari-server/ambari-server-check-database.log 2016-12-20 00:34:00,131  INFO - ******************************* Check database completed ******************************* 2016-12-20 00:35:26,917  INFO - Checking DB store version 2016-12-20 00:35:30,076  INFO - DB store version is compatible  But if logged into the ambari page, "start services" option is in disabled mode. How to start the services..   Thanks!!
