当我尝试:
hadoop fs -mkdir hdfs://HName:10001/data/testFolder
我得到:
mkdir: Call From HName/192.168.21.129 to HName:10001 failed on connection except
ion: java.net.ConnectException: Connection refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused
请注意: - 当JPS
我看到所有应该在名称节点上的服务时,在数据节点上我看到所有应该在那里的服务。-我可以ssh
从任何节点到它自己和任何其他没有密码的节点。-我在一个名称节点和三个数据节点上运行Hadoop 2.7.3
当我尝试时:
sudo netstat -ntap | grep 9000
我得到:

可能是什么问题呢?在哪里看?
