About

There was two big release:

• the original Hive Server (sometimes called Thrift server or HiveServer1).
• and the HiveServer2. See HiveServer2+Overview. The HiveServer was introduced in Hive 1.2.1.

The original HiveServer has several concurrency issues and lacks several features available in HiveServer2.
