Subject [jira] Created: (HADOOP-5196) avoiding unnecessary byte[] allocation in SequenceFile.CompressedBytes and SequenceFile.UncompressedBytes
Date Sat, 07 Feb 2009 02:43:02 GMT
avoiding unnecessary byte[] allocation in SequenceFile.CompressedBytes and SequenceFile.UncompressedBytes
---------------------------------------------------------------------------------------------------------

                 Key: HADOOP-5196
                 URL: https://issues.apache.org/jira/browse/HADOOP-5196
             Project: Hadoop Core
          Issue Type: Improvement
          Components: io
    Affects Versions: 0.21.0
            Reporter: Hong Tang
            Priority: Minor


SequenceFile.CompressedBytes and SequenceFile.UncompressedBytes are used by the SequenceFile's
raw bytes reading/writing API. The current implementation does not reuse the internal byte[]
and causes unnecessary buffer allocation and initializaiton (zeroing the buffer).
