Everything works fine until we setup external DB(mysql) for hive by running:
ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar
which is the step 17of the instruction: http://docs.hortonworks.com/HDPDocuments/Ambari-184.108.40.206/bk_upgrading_Ambari/content/_upgrade_ambari....
Can you provide a little more detail around what exactly is hanging? screenshots, logs, etc would all be greatly appreciated. Thanks
Can you make sure /usr/share/java/mysql-connector-java.jar is accessible by the user that the Ambari Server is running as?
+1 on getting logs. I experienced similar behavior from Ambari and the answer was in Ambari Server logs. When the server hangs, can you check ambari server logs and provide that / look for any clues?
Please see this doc for configuring external db and make sure that you have the connector files in place.
