Re: Getting free and used space

Hi there.

I noticed that function getUsed() is no longer present in Hadoop 0.20.

What are the new functions of getting used and free space in DFS, and are
they working correctly, without any special admin permissions?

Thanks!

Both DFSClient and DistributedFileSystem have this method:
  public DiskStatus getDiskStatus() throws IOException {

You can obtain usage data from:
  public static class DiskStatus {
which is defined in
src/hdfs/org/apache/hadoop/hdfs/DistributedFileSystem.java
