Vinayakumar B commented on HDFS-8545:
-------------------------------------
On a second thought,
along with new overloaded API, how about refactoring current {{getUsed()}} also
to get the usage from the contentsummary than iterating through the list of
files recursively.
{code} /** Return the total size of all files in the filesystem.*/
public long getUsed() throws IOException{
Path path = new Path("/");
return getContentSummary(path).getLength();
}{code}
This would improve the performance as well.
[~wheat9], what do you say?
> Add an API to fetch the total file length from a specific path, apart from
> getting by default from root

> 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" .
