fred521 commented on issue #3633: unable to connect presto and hive through presto jdbc interpreter URL: https://github.com/apache/zeppelin/pull/3633#issuecomment-583938090 Hi @zjffdu I think zeppelin jdbc interpreter default 'url' in the properties, but is invalid in the presto jdbc driver see the [PrestoDriverUri.java] (https://github.com/prestodb/presto/blob/303e640f5da27a8c3785aae2f4129fa2293d062f/presto-jdbc/src/main/java/com/facebook/presto/jdbc/PrestoDriverUri.java#L324) and [ConnectionProperties.java](https://github.com/prestodb/presto/blob/303e640f5da27a8c3785aae2f4129fa2293d062f/presto-jdbc/src/main/java/com/facebook/presto/jdbc/ConnectionProperties.java#L58) the same as the hive in the jdbc interpreter. see the jira exception https://issues.apache.org/jira/browse/ZEPPELIN-4601
