> Support dynamic service discovery for HiveServer2
> -------------------------------------------------
>
> Key: HIVE-7935
> URL: https://issues.apache.org/jira/browse/HIVE-7935
> Project: Hive
> Issue Type: New Feature
> Components: HiveServer2, JDBC
> Affects Versions: 0.14.0
> Reporter: Vaibhav Gumashta
> Assignee: Vaibhav Gumashta
> Fix For: 0.14.0
>
> Attachments: HIVE-7935.1.patch, HIVE-7935.2.patch, HIVE-7935.3.patch,
> HIVE-7935.4.patch
>
>
> To support Rolling Upgrade / HA, we need a mechanism by which a JDBC client
> can dynamically resolve an HiveServer2 to connect to.
> *High Level Design:*
> Whether, dynamic service discovery is supported or not, can be configured by
> setting HIVE_SERVER2_SUPPORT_DYNAMIC_SERVICE_DISCOVERY. ZooKeeper is used to
> support this.
> * When an instance of HiveServer2 comes up, it adds itself as a znode to
> ZooKeeper under a configurable namespace (HIVE_SERVER2_ZOOKEEPER_NAMESPACE).
> * A JDBC/ODBC client now specifies the ZooKeeper ensemble in its connection
> string, instead of pointing to a specific HiveServer2 instance. The JDBC
> driver, uses the ZooKeeper ensemble to pick an instance of HiveServer2 to
> connect for the entire session.
> * When an instance is removed from ZooKeeper, the existing client sessions
> continue till completion. When the last client session completes, the
> instance shuts down.
> * All new client connection pick one of the available HiveServer2 uris from
> ZooKeeper.
