org.apache.hadoop.mapreduce.lib.input.InvalidInputException:输入路径不存在：hdfs://localhost:9000/user/root/in

有人能告诉我到底是什么问题，我该如何解决？我是新用户

错误

root@priyal-Inspiron-N5030:/home/priyal# hadoop dfs -copyFromLocal in /in
root@priyal-Inspiron-N5030:/home/priyal# hadoop jar /usr/local/hadoop/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.6.0.jar wordcount in out

/user/root/in
在您的HDFS中不是prsrent。您可以使用简单的web UI浏览文件系统

然后单击实用程序下拉菜单->浏览文件系统。并检查您的折叠式雇佣关系，即/user/root/in

如果它不存在，您可以使用命令创建文件夹

org.apache.hadoop.mapreduce.lib.input.InvalidInputException: Input path does not exist: hdfs://localhost:9000/user/root/in
现在尝试执行复制命令

hadoop dfs -mkdir hdfs://localhost:9000/user/root/in
希望这对您有所帮助：）

hadoop dfs -copyFromLocal /local/path/of/source/file hdfs://localhost:9000/user/root/in
