Description

When using du command in dfs shell, I noticed that the return value of du command is inconsistent according to the document.]

The du returns three columns with the following format:

size disk_space_consumed_with_all_replicas full_path_name 

However, when executing the following commands on 4 nodes 2.10.2 hdfs cluster

> bin/hdfs dfs -mkdir /uYePouSe
> bin/hdfs dfs -put -f -p -d /tmp/local_folder/Gm /uYePouSe/

> bin/hdfs dfs -du -s -x /uYePouSe/Gm
0  /uYePouSe/Gm

The results are

0  /uYePouSe/Gm

however, the expected results should be 3 columns:

0  0  /uYePouSe/Gm

 

The fix should probably be modifying the document or adding a patch to the du command to correct the return results.
