Apache Drill JDBC无法在Windowns 10上使用所有默认值

Question

我在使JDBC连接工作时遇到问题。非常感谢你的帮助。

1. 在Windows 10 Pro，ODBC驱动程序上安装Drill，启动并运行 本地节点（如 https://drill.apache.org/docs/drill-in-10-minutes/）
2. 可以使用ODBC从Drill Explorer连接和查询。

JDBC：



别名：



但是当我尝试从（https://drill.apache.org/docs/using-jdbc-with-squirrel-on-windows/）中的SQuirreL连接时，它无效。 我使用/jars/jdbc-driver/drill-jdbc-all-.jar进行JDBC连接。

Answer 1

我认为你不能使用ZooKeeper“本地”，因为你是通过JDBC来自“外部”源。尝试将其更改为“localhost”或您的主机名。

Answer 2

最后，这篇文章有助于解决我的问题。 Apache Drill - connection to Drill in Embedded Mode [java]

通过使用，jdbc：drill：drillbit = 192.xxx.xxx.xxx，当钻取运行时，我可以成功连接..
