Allen Wittenauer commented on HADOOP-7713:
------------------------------------------
I think from a useability perspective, this issue falls into the same sort of
category as the fsck dot code: the headers should default to on with an option
to turn them off. Yes, I realize this makes it an incompatible change which
would only make it eligible for trunk.
Anyone have any other opinions?

> These commands should label the output columns:

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