title: HDFS free space available command
body: <p>Is there a hdfs command to see available free space in hdfs. We can see that through browser at master:hdfsport in browser , but for some reason I can't access this and I need some command.
  I can see my disk usage through command ./bin/hadoop fs -du -h but cannot see free space available.</p>
