nodejs 通过 phoenix 和 druid 连接到 hbase

Question

我有 Phoenix 安装了 phoenix-4.3.1 并通过 sqline 成功连接到 hbase 在属于集群一部分的机器上以及不属于集群且没有 hadoop 组件的机器上；只需访问 zookeeper sqlline 访问没问题，但是通过 druid 通过 app (npm) 连接会出错

我找到了 npm https://github.com/gaodazhu/phoenix-client

我得到以下内容

您是否尝试过在 Phoenix 中创建一个“TEST”表？并确保在“TEST”表中插入一些行。
