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).
