我正在尝试导入happybase，但在连接时收到以下错误消息。我已经运行了 Hadoop 伪节点集群和 Hbase。安装的组件版本如下，Hadoop版本 - 1.0.4 Hbase版本 - 0.94.4 happybase -0.4

有人可以查看下面的例外情况并让我知道，如果有任何节俭的特定设置或任何解决此问题的指导。

谢谢你。

在尝试连接之前，请确保您已启动 Thrift 服务器。

hbase thrift start -threadpool

trift 服务器必须启动并运行。您的连接也必须打开：

nohup hbase thrift start &

使用前在python中打开连接：

connection.open()

例子：

#!/usr/bin/python
import happybase
connection = happybase.Connection('localhost', autoconnect=False)
connection.open()

这对我有用：

sudo server hbase-thrift restart
