本文介绍HiveServer2的配置参数，包括Thrift接口的最小和最大工作线程数、异步执行线程池大小及超时时间等，并提供启动命令。HiveServer2支持远程客户端执行Hive查询并获取结果。

HiveServer2 (HS2) is a server interface that enables remote clients to execute queries against Hive and retrieve the results. The current implementation, based on Thrift RPC, is an improved version of HiveServer and supports multi-client concurrency and authentication. It is designed to provide better support for open API clients like JDBC and ODBC.
