Subject [jira] Created: (HADOOP-2285) TextInputFormat is slow compared to reading files.

TextInputFormat is slow compared to reading files.
--------------------------------------------------

                 Key: HADOOP-2285
                 URL: https://issues.apache.org/jira/browse/HADOOP-2285
             Project: Hadoop
          Issue Type: Bug
          Components: mapred
    Affects Versions: 0.15.0
            Reporter: Owen O'Malley
             Fix For: 0.16.0


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.
