ERROR in datanode execution while running Hadoop first time in Windows 10
问题 I am trying to run Hadoop 3.1.1 in my Windows 10 machine. I modified all the files: hdfs-site.xml mapred-site.xml core-site.xml yarn-site.xml Then, I executed the following command: C:\hadoop-3.1.1\bin> hdfs namenode -format The format ran correctly so I directed to C:\hadoop-3.1.1\sbin to execute the following command: C:\hadoop-3.1.1\sbin> start-dfs.cmd The command prompt opens 2 new windows: one for datanode and another for namenode. The namenode window keeps running: 2018-09-02 21:37:06
