Question

我试图在每个regionserver上运行Thrift（用于mapreduce输入以及将来的负载平衡）。

使用12/01/30 15:52:32 INFO client.HConnectionManager$HConnectionImplementation: getMaster attempt 9 of 10 failed; no more retrying.

启动Thrift服务器失败

有一条到主机的路由（ping成功），hbase master在默认端口上运行（并且使用lsof -i：60000确认存在），但我还没有

12/01/30 15:52:32 INFO client.HConnectionManager$HConnectionImplementation: getMaster attempt 9 of 10 failed; no more retrying.

Answer 1

也许在hbase主机上你遇到防火墙问题或绑定到错误的网络接口？为了确保不是这种情况？我会在你安装thrift的同一台机器上尝试netcat nc，telnet或类似的东西，看看它们是否可以连接到这个主机/端口。

Thrift无法在regionservers上运行：getMaster尝试失败并出现java.net.ConnectException：Connection被拒绝
