Description

These commands should label the output columns:

hadoop dfs -count <dir>...<dir>
hadoop dfs -count -q <dir>...<dir>

Current output of the 2nd command above:

% hadoop dfs -count -q /user/foo /tmp
        none             inf         9569         9493         6372553322 hdfs://nn1.bar.com/user/foo
        none             inf          101         2689       209349812906 hdfs://nn1.bar.com/tmp

It is not obvious what these columns mean.
