I know "du -h" command gives the disk usage in human readable format. But please let me know what are the two values showing up while using the "du -h" command on HDFS filesystem for my Hadoop Cluster.
[hduser@node2 ~]$ sudo -u hdfs hdfs dfs -du -h /
6.3 K 768.0 M /hbase
0 0 /tmp
371.6 M 743.2 M /user
Output for directories inside Hbase:
