Jakob Homan commented on HADOOP-4917:
-------------------------------------
Linux doesn't justify across directories on recursive ls either:
{noformat}

It could potentially be quite costly to gather the maximum spaces needed for
justification across a very large namespace. Perhaps it would be better to
bring lsr closer in line with Unix, separating each listed directory with a
header and allowing each directory to be justified relative to itself?
