How to remove files inside the hadoop directory at once?

Question

I want to remove all the files containes in hadoop directory, without removing the directory itself. I've tried using rm -r but it removed the whole directory.

Answer 1

Please include a wildcard character * after the desired folder you want to delete, to avoid deleting the parent folder. Please look at the example below:

hdfs dfs -rm -r /home/user/folder/*

Answer 2

参考上一个答案，你需要引用星号： hdfs dfs -rm -r "/home/user/folder/*"

Answer 3

Use hdfs command to delete all files in it. For example, if your hadoop path is /user/your_user_name/* then use asterisk to delete all files inside the specific folder.

hdfs dfs -rm -r /user/your_user_name/*
