Milind Bhandarkar updated HADOOP-735:
-------------------------------------
Status: Open (was: Patch Available)
I have removed this patch, because it creates incompatibility between
serialization formats for buffer in c++ and java. I will upload the correct
patch soon. The new patch will also eliminate the need to modify the
WritableComparator's read* static methods.
> The underlying data structure, ByteArrayOutputStream, for buffer type of
> Hadoop record is inappropriate

> Key: HADOOP-735
> URL: https://issues.apache.org/jira/browse/HADOOP-735
> Project: Hadoop
> Issue Type: Bug
> Components: record
> Affects Versions: 0.9.2
> Reporter: Runping Qi
> Assigned To: Milind Bhandarkar
> Fix For: 0.11.0
>
>
> 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.
