Here’s a full, step‑by‑step guide to working with – covering connection URLs, configuration, authentication, and code examples. 1. Hive Server Address Formats a) Hive Server 2 (HS2) – Default since Hive 0.11 HS2 supports multiple clients, including JDBC (Java). String url = "jdbc:hive2://hive-secure
beeline -u "jdbc:hive2://<host>:<port>/<db>;principal=hive/_HOST@REALM" If beeline works, your Java code will too. | Component | Value / Pattern | |--------------------|-------------------------------------------------------| | JDBC prefix | jdbc:hive2:// | | Host:Port | <hive-server>:10000 (or HTTP 10001) | | Auth param | auth=noSasl / principal=... / user=... | | Transport mode | binary (default) or transportMode=http | | HA (ZooKeeper) | serviceDiscoveryMode=zooKeeper + ZooKeeper hosts | | Java driver | org.apache.hive.jdbc.HiveDriver (auto-loaded) | | | Transport mode | binary (default) or
Always match hive-jdbc version with your server’s Hive version, and test first with beeline .
Use beeline (Hive’s JDBC client) to validate your address:
a) No SASL (plain, insecure – test only) jdbc:hive2://host:10000/default;auth=noSasl Use empty user/pass. b) Kerberos (production, secure) jdbc:hive2://host:10000/default;principal=hive/_HOST@REALM.COM Java side:
