Hi, I have the same issue when I create a connection to PostgreSQL, the reason is make sure your driver class name is correct.
For example my HIVE driver name is "com.amazon.hive.jdbc4.HS1Driver" Also make sure your URL format is correct :) My PostgreSQL setting is like this: <http://apache-nifi-developer-list.39713.n7.nabble.com/file/n2873/Screen_Shot_2015-09-18_at_2.png> Database Connection URL : Format must coorect, ur hive format should like this: jdbc:hive2://<server IP>:10000/default Database Driver Class Name: class name must correct, if you downloaded driver from website, take a look see if people write class name there. Others, please post a screenshot and we can figure out what is the reason :) Best Regards QXU -- View this message in context: http://apache-nifi-developer-list.39713.n7.nabble.com/NIFI-DBCP-connection-pool-not-working-for-hive-tp2863p2873.html Sent from the Apache NiFi Developer List mailing list archive at Nabble.com.
