凤凰错误：hbase 表未定义，即使它存在

Question

我正在尝试使用 localhost:2181 的 zookeeper 访问在本地计算机上运行的 hbase。我安装了 phoenix-3.3.1-bin 并试图访问一个已经存在的 hbase tabe，但不能。因此，为了测试，我使用 phoenix 命令行创建了一个表，并在运行 !tables 命令时查看它。但是当我运行 selet 命令时，它显示错误。

这就是我正在做的，我使用的是 mac，hbase-0.94.26。同样的事情也发生在 squirrel-sql 客户端上。

. . . . . . . . . . . . .>     txn_count bigint CONSTRAINT pk PRIMARY KEY (host, created_date) );
No rows affected (1.82 seconds)

如果您在 HBase 中使用小写字母创建表，则需要将表名括在引号中。否则，Phoenix 会将表名转换为大写，并且找不到您的表。
