使用sqoop将MySQL数据导入hdfs时报错HADOOP

查看报错内容

原因是mapred-site.xml配置文件少了内容

  yarn.app.mapreduce.am.env
  HADOOP_MAPRED_HOME=${full path of your hadoop distribution directory}


  mapreduce.map.env
  HADOOP_MAPRED_HOME=${full path of your hadoop distribution directory}


  mapreduce.reduce.env
  HADOOP_MAPRED_HOME=${full path of your hadoop distribution directory}

将上面内容复制到配置文件中，将${full path of your hadoop distribution directory}改成hadoop classpath 的完整路径，如上图

改完了以后
