hadoop : failed on connection exception:

原创 Hadoop 作者:xiaoyan5686670 时间:2016-09-01 23:06:32 0 删除 编辑
[hadoop@qxy1 logs]$ hadoop fs -ls /
16/09/01 15:58:32 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
ls: Call From qxy1/192.168.233.159 to qxy1:8020 failed on connection exception: java.net.ConnectException: Connection refused; For more details see:  http://wiki.apache.org/hadoop/ConnectionRefused


从wiki上没有找到答案。最后解决办法:我在      hdfs-site.xml配置如下:        
  dfs.namenode.rpc-address
  qxy1:8020
 

此处要与 core-site.xml保持一致 :hdfs://qxy1的端口是      


  fs.defaultFS
  hdfs://qxy1
  The name of the default file system.  A URI whose
  scheme and authority determine the FileSystem implementation.  The
  uri's scheme determines the config property (fs.SCHEME.impl) naming
  the FileSystem implementation class.  The uri's authority is used to
  determine the host, port, etc. for a filesystem.
