Amareshwari Sriramadasu updated HADOOP-3040:
--------------------------------------------
Attachment: patch-3040.txt
Added a testcase with input having 3 lines:
1. First line has key\tvalue
2. Second line starts with a tab. i.e empty key and whole line is value.
3. Third line doesnt have any tab. Then whole line is the key.
> Streaming should assume an empty key if the first character on a line is the
> seperator (stream.map.output.field.separator, by default, tab)
