Arun C Murthy updated HADOOP-2285:
----------------------------------
Status: Open (was: Patch Available)
Minor nit: this patch removes a public constructor rather than add a new one:
{noformat}
- public LineRecordReader(InputStream in, long offset, long endOffset)
+ public LineRecordReader(InputStream in, long offset, long endOffset,
+ Configuration job)
{noformat}
> TextInputFormat is slow compared to reading files.

> The LineRecordReader reads from the source byte by byte, which seems to be
> half as fast as if the readLine method was defined on the memory buffer
> directly instead of as an InputStream.
