我正在按照教程安装 hadoop: http: //www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/ 现在我被困在“复制本地示例数据”到 HDFS”步骤。
我得到的连接错误:

Bad connection to FS. command aborted. exception: Call to localhost/127.0.0.1:54310 failed on connection exception: java.net.ConnectException: Connection refused
这已经和这个问题差不多了: Errors while running hadoop
现在的重点是,我已经禁用了 ivp6,如那里和上面的教程中所述,但它没有帮助。有什么我一直想念的吗?
编辑:
我在第二台机器上用新安装的 ubuntu 重复了该教程,并逐步进行了比较。事实证明,在 hduser 的 bashrc 配置中存在一些错误。后来效果很好...
