我尝试使用代码通过jdbc连接到phoenix
Connection r = DriverManager.getConnection("jdbc:phoenix:serverName:8765/hbase");
执行错误

在 ZooKeeper 中我发现了另一个被忽略的异常:

驱动程序版本4.9.0-HBase-1.1
来自 Hbase shell 1.1.2.2.5.0.0-1245 的版本
PS:我可以使用 HBase 客户端 API 直接连接到 Hbase
最佳答案
连接字符串有错误。
应该是jdbc:phoneix[:zk_quorum][:zk_port][:zk_hbase_path]
就我而言jdbc:phoenix:zookeperServerName:2181:/hbase-unsecure
关于java - 无法使用 jdbc 通过 phoenix 连接到 HBase。错误 NONODE，代码 101，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41589017/
