Question

我正在尝试通过Squirrel客户端连接到Phoenix。我在Squirrel日志中收到以下日志。日志表明已建立到zooperkeeper的ClientConnection，但是当使用Timeout异常建立SQLClient连接时，它会失败。

我已将凤凰客户端jar复制到Squirrel的lib目录中，并且驱动程序已成功注册。此外，当我在localhost中运行SQLLine.py实用程序时，它成功地将SQL命令行加载到Phoenix，我可以运行命令。还将凤凰核心jar添加到$ HBASE_HOME / lib文件夹中。

我遇到同样的问题，但还没有找到解决方案，但我设法使用“瘦”客户端。

启动queryserver https://phoenix.apache.org/server.html应该侦听端口8765
将JAR phoenix-4.6.0-HBase-1.1-thin-client复制到Squirel lib文件夹
创建新驱动程序，类名为“org.apache.phoenix.queryserver.client.Driver”
连接此驱动程序（我的URI：jdbc：phoenix：thin：url = http://docker:8765）
