There isn't one, and this ought to be the only way (unless you're
willing to build an infrastructure that can keep a block->lines meta
info mapping for optimally fetching a single block given a line # --
but that's overkill?).

I use
hadoop dfs -text | head-n
hadoop dfs -text | tail-n
to browse the n-th line from the head or from the tail. But it is slow
when the file is large. Is there any command that goes directly to a
specific line in dfs?
