错误：无法建立与jdbc：hive2：// localhost：10000 / metastore的连接：

Question

我正在将Cloudera Docker容器与Beeline CLI一起使用。 我正在尝试通过以下方式访问metastore数据库：

!connect jdbc:hive2://localhost:10000/metastore hive cloudera org.apache.hive.jdbc.HiveDriver

但不是成功的连接，而是引发响应：

Error: Could not establish connection to jdbc:hive2://localhost:10000/metastore: Required field 'client_protocol' is unset! Struct:TOpenSessionReq(client_protocol:null, configuration:{use:database=metastore}) (state=08S01, code=0)

这是我的hive-site.xml文件：

`<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>`

`<configuration>`

  `<!-- Hive Configuration can either be stored in this file or in the hadoop configuration files  -->
  <!-- that are implied by Hadoop setup variables.                                                -->
  <!-- Aside from Hadoop setup variables - this file is provided as a convenience so that Hive    -->
  <!-- users do not have to edit hadoop configuration files (that may be managed as a centralized -->
  <!-- resource).`                                                                                 -->

我已经尝试使用jdbc:thrift://localhost:10000/*和jdbc:hive2://localhost:9083/*和jdbc:thrift://localhost:9083/*。 最后一个抛出NullPointerException，第一个和第二个拒绝与java.net.SocketException连接。

我也尝试用不同的方式初始化metastore数据库 /usr/lib/hive/scripts/metastore/upgrade/mysql/hive-schema-n.n.n.mysql.sql 脚本，包括0.10.0、1.1.0（这是我的蜂巢版本）

使用--privileged=true选项运行容器。

服务mysqld，hive-metastore和hive-server2在默认端口上启动。
