./bin/hdfs dfs –rm –r input  也是"-"符号错误

cd /home/stu/

vim myLocalFile.txt

文件添加后再回到原来的目录下

cd /usr/local/hadoop

3

./bin/hdfs dfs -put /home/stu/file1.txt  /user/stu
./bin/hdfs dfs -put /home/stu/file2.txt  /user/stu
./bin/hdfs dfs -put /home/stu/file3.txt  /user/stu
./bin/hdfs dfs -put /home/stu/file4.abc  /user/stu

./bin/hdfs dfs -put /home/stu/file5.abc  /user/stu

 

这两个文件夹要删掉

./bin/hdfs dfs -rm -r  /user/stu/input2
./bin/hdfs dfs -rm -r  /user/stu/output
