Question

我正在尝试使用Happybase创建表。首先，输入以下命令以运行Hbase和Thrift：

start-hbase.sh
hbase thrift start &

一旦运行，我打开Python的命令提示符并键入以下内容：

import happybase as hb
connection = hb.Connection()
connection.open()

但是，当我尝试创建表时：

connection.create_table(
'mytable',
{'cf1': dict(max_versions=10),
 'cf2': dict(max_versions=1, block_cache_enabled=False),
 'cf3': dict(),  # use defaults
}

我收到以下我不理解的错误。

您需要指定服务器地址，可能还需要指定端口：

connection = hb.Connection(SERVER, PORT)

您可能会省略端口值，因为默认值很可能会匹配，但以防万一检查您的二手服务器正在监听哪个端口并将其指定为数字值

无法在Python中使用Happybase创建简单表
