How to find in HDFS the creation date of a file

Question

I need to find the creation date of a file or a folder in a hdfs directory. For example with:

hadoop fs -ls /user/myUser/ 

I get a list of files and directories in the path /user/myUser/ with the modification date. I want to find the creation date for each entry.

您无法获得创建时间，但是可以获得修改时间。但是，在HDFS文件中，文件通常只创建一次，因此修改时间可能与创建时间相同。您可以使用-stat command并运行：

hadoop fs -stat "%y" /user/myUser/
hadoop fs -stat "%Y" /user/myUser/

在源Stat.java中找到所有受支持的选项：
