Harsh J commented on MAPREDUCE-3991:
------------------------------------
(Second QA run came later, so could not apply, after trunk commit had gone in. It was just

> Streaming FAQ has some wrong instructions about input files splitting

> Steaming docs say, at: http://hadoop.apache.org/common/docs/current/streaming.html#How+do+I+process+files%2C+one+per+map%3F

get one file name as input."
> This is incorrect, as a file isn't split by lines, rather by size - for MR.
