Haohui Mai commented on HDFS-8545:
----------------------------------

Why this should be a function in FileSystem instead of a shell command?

> Currently by default in FileSystem#getUsed() returns the total file size from root. 
> It is good to have an api to return the total file size from specified path ,same as
we specify the path in "./hdfs dfs -du -s /path" .
