Question

经过艰苦的努力，我设法使用Jersy -Jax-RS为我的Rest服务提供了一个有效的代码。

我的项目包括使用hadoop数据库的简单数据库操作。不知怎的错误如：

组织/阿帕奇/蜂巢/服务/ RPC /节俭/ TCLIService $ IFACE

使用-e开关重新运行maven

未找到类org.apache.hive.jdbc.HiveDriver

问题是：Hadoop数据库连接需要许多其他支持依赖项，并附带hive-jdbc jar。

请按照POM.xml文件启用所有操作以连接到Hadoop数据库。

Answer 1

hive-jdbc是您通过JDBC连接到Hive所需的唯一依赖项，应该找到jdbc驱动程序类。目前尚不清楚你是如何运行代码的

它包含libthrift本身，并且不需要Hadoop依赖项，但如果你确实添加了这些依赖项，那么版本必须匹配。不要混用Hadoop 1.x和Hadoop 2.x

此外，您必须匹配在Hadoop / Hive环境中运行的实际版本。 Hadoop 2.5和Hive 0.13已有几年了

在Jax中连接Hadoop（Hive apis）数据库 - RS休息服务 - Netbeans
