我已经安装了 CDH 4.2.1，现在我正在尝试访问 HUE Web UI首次。我输入新的用户名和密码，点击Sign Up ，然后等待，等待 20 分钟，什么都没有发生。如果我打开另一个窗口并尝试访问登录页面，则会收到数据库已锁定的消息。
我在单个节点上运行。以下是第二个窗口的错误消息:

任何的想法？
谢谢，

最佳答案
这里的错误意味着它正在尝试连接到 Sqlite 并失败，因为第一个连接仍未完成(并且 Sqlite 不是并发的)所以它在这里不是很有用。
如果有更多信息，请查看色调日志，尤其是“runcpserver.log”。
在环境中添加“export DESKTOP_DEBUG=1”并重新启动 Hue 可能会提供更多详细信息。
我会继续 http://HUE_SERVER:HUE_PORT/dump_config ，查看“数据库”值并删除文件并运行/opt/cloudera/parcels/CDH-4.2.1-1.cdh4.2.1.p0.5/share/hue syncb 或同步数据库(如果在 CM 中)。
它将重新创建数据库并确保没有其他进程正在使用它。
如果它仍然不起作用，我会尝试 MySQL:http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH4/latest/CDH4-Installation-Guide/cdh4ig_topic_15_8.html
