Radoop 的访问被拒绝问题。将 RapidMiner 与 Cloudera Quickstart VM 连接
Access Denied Issue with Radoop. Connecting RapidMiner with Cloudera Quickstart VM
我已经在 PC 上安装了一个 Quickstart Cloudera VM，其中包含所有服务 运行正在分配 14G 内存。在虚拟机 运行 正在运行的桌面上（不在虚拟机中），我安装了 RapidMiner，以便在 Radoop 进入生产服务器之前对其进行测试。我使用了 RapidMiner 中的 "Import from Cluster Manager"，它从 CHD 中检索了正确的配置。当我 运行 完整测试时，当 rapidminer 测试它是否可以在 Hive 上创建 table 等时，我 运行 拒绝访问。

也许这只是我可以在 CDH 中进行的配置更改，例如修改 Hive 配置，或者允许 RapidMiner read/write。
长话短说：在 Cloudera Quickstart 5.13 VM 上，您应该在 Global 选项卡和 "Hive username" 以及 Hive 选项卡上为 "Hadoop username" 使用相同的用户名。
