【问题描述】：
我正在尝试使用 DBVisualizer 建立与 Phoenix 的连接，但出现以下错误
以下步骤在这里给出 https://community.hortonworks.com/articles/19016/connect-to-phoenix-hbase-using-dbvisualizer.html
之后出现如下错误
ERROR 103 (08004): Unable to establish connection
当检查 DBVisualizer 的错误日志时，我看到以下内容
2019-07-22 12:53:18.890 INFO 903 [ExecutorRunner-pool-3-thread-1 - H.Ĵ] Exception while connecting Hbase

该错误表明缺少需要在 DbVisualizer 的工具->驱动程序管理器中加载的 jar 文件。我建议您尝试连接，然后在 DbVisualizer 中的 Help->Contact Support 中打开支持票证。
