HUE网络用户界面不会第一次登录

问题描述：

我已经安装了CDH 4.2.1，现在我试图首次访问HUE Web UI。我输入一个新的用户名和密码，点击Sign Up，然后等待，等20分钟没有任何反应。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。HUE网络用户界面不会第一次登录

我正在单个节点上运行。以下是第二个窗口的错误消息：

任何想法？

谢谢，

答

错误在这里意味着它试图连接到SQLite和作为第一个连接仍然没有结束（和SQLite是不是并发），所以在这里也不是很有益的失败。

如果会看在色相日志，尤其是“runcpserver.log”如果有更多的信息。

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。

我将继续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如果在CM中，则使用syncb或同步数据库。

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
