运输异常

Question

我正在尝试导入happybase，但在连接时会收到以下错误消息。 我有Hadoop伪节点集群和Hbase已经运行。 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告知我们，如果有任何节俭特定设置或任何指导来解决此问题。

谢谢。

Answer 1

确保在尝试连接之前启动了thrift服务器。

hbase thrift start -threadpool

Answer 2

thrift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()

示例：

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

Answer 3

connection = happybase.Connection('localhost','2181')

Answer 4

这对我有用：

sudo server hbase-thrift restart
