Owen O'Malley updated HADOOP-735:
---------------------------------
Component/s: record
(was: io)
Description:
With ByteArrayOutputStream as the underlying data structure for a buffer, the
user is forced to convert it into a byte [] object in order to do any
operations other than sequence append on the buffer. The convertion will create
a new copy of bytes. That will cause huge performance problem.
It seems BytesWritable is a better replacement.
