Jdbc 将HiveServer2指向用于配置单元测试的最小群集

我一直想对我开发的一些代码进行配置单元集成测试。我需要的测试框架的两个主要要求：

它需要使用Cloudera版本的Hive和Hadoop （最好是2.0.0-cdh4.7.0）

它必须是所有本地的。Hadoop集群和Hive的意义 服务器应该在测试开始时启动，运行一些查询， 测试结束后再拆卸

所以我把这个问题分为三个部分：

获取HiveServer2部分的代码（我决定使用JDBC） Thrift服务客户端上的连接器）

获取用于构建内存中MapReduce集群的代码（我决定为此使用MinimerCluster）

设置上述（1）和（2）以相互配合 通过查看许多资源，我得以避开。其中一些非常有用的是：

对于第（2）项，我在StackOverflow中关注了这篇优秀的文章：

到目前为止，一切顺利。此时，我的Maven项目中的pom.xml（包括上述两项功能）看起来如下所示：

我希望（3）将通过上述方法中的以下代码行解决：

    Connection hiveConnection = DriverManager.getConnection(
            "jdbc:hive2:///", "", "");

但是，我得到了以下错误：

java.sql.SQLException: Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask
    at org.apache.hive.jdbc.Utils.verifySuccess(Utils.java:161)
    at org.apache.hive.jdbc.Utils.verifySuccessWithInfo(Utils.java:150)
    at org.apache.hive.jdbc.HiveStatement.execute(HiveStatement.java:207)
    at com.ask.nkelkar.hive.HiveUnitTest.testHiveMiniDFSClusterIntegration(HiveUnitTest.java:54)

有人能告诉我我需要做些什么吗？/我做错了什么才能让这项工作正常进行

另外，我将和项目视为选项，但我无法将它们与Cloudera版本的Hadoop一起使用。

您的测试在第一个

创建表
语句中失败。配置单元正在无效地抑制以下错误消息：

file:/user/hive/warehouse/test is not a directory or unable to create one

配置单元正在尝试使用文件系统中不存在的默认仓库目录
/user/Hive/warehouse
。您可以创建目录，但对于测试，您可能希望覆盖默认值。例如：

import static org.apache.hadoop.hive.conf.HiveConf.ConfVars;
...
System.setProperty(ConfVars.METASTOREWAREHOUSE.toString(), "/Users/nishantkelkar/IdeaProjects/" +
            "nkelkar-incubator/hive-test/target/hive/warehouse");

谢谢你回复这个帖子！现在它不再给我那个错误了。您是对的，它需要查看/warehouse文件夹才能继续。我希望Hive的错误消息在语义上更加详细。如果你能看一看，我将不胜感激。谢谢大家!--
import static org.apache.hadoop.hive.conf.HiveConf.ConfVars;
...
System.setProperty(ConfVars.METASTOREWAREHOUSE.toString(), "/Users/nishantkelkar/IdeaProjects/" +
            "nkelkar-incubator/hive-test/target/hive/warehouse");
