Jothi Padmanabhan commented on HADOOP-6224:
-------------------------------------------

Actually, you are right -- the ownership of the internal buffer gets muddled 
with this patch. 
What we actually need in MAPREDUCE-318 was a way to create and handle streams 
based on memory buffers. I created HADOOP-6226 to handle this and will revert 
the changes to DataOutputBuffer in that patch.

> Add some utility methods to Text and DataOutputBuffer to be used by 
> MAPREDUCE-318
