我尝试通过代码
通过jdbc连接到phoenixConnection r = DriverManager.getConnection("jdbc:phoenix:serverName:8765/hbase");
执行错误

驱动程序版本4.9.0-HBase-1.1
Hbase shell 1.1.2.2.5.0.0-1245的版本
PS：我能够直接使用HBase客户端API
连接到Hbase答案 0 :(得分：2)
连接字符串中有错误。
应为jdbc:phoneix[:zk_quorum][:zk_port][:zk_hbase_path]
就我而言jdbc:phoenix:zookeperServerName:2181:/hbase-unsecure
