Release Note

This patch adds a web UI to HiveServer2, and introduced 3 new configurations: hive.server2.webui.host, hive.server2.webui.port, and hive.server2.webui.max.threads. The web UI can be used to access the HiveServer2 configuration, local logs, metrics. It can also be used to check some information about those active sessions and queries being executed, etc..

The web UI by default listens to port 10002, which can be configured with setting: hive.server2.webui.port.

This patch can be disabled by setting hive.server2.webui.port to 0 or a negative number.
