Subject [jira] [Commented] (HDFS-8545) Add an API to fetch the total file length from a specific path, apart from getting by default from root
Date Wed, 09 Sep 2015 11:46:45 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8545?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14736709#comment-14736709

Vinayakumar B commented on HDFS-8545:
-------------------------------------

Changes looks good to me.

One improvement is, you can refactor existing {{getUsed()}} method and re-use the code of
new API. just like below.
{code}  /** Return the total size of all files in the filesystem.*/
  public long getUsed() throws IOException{
    Path path = new Path("/");
    return getUsed(path);
  }{code}

Test failure seems unrelated.

> 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" .
