Konstantin Shvachko reopened HADOOP-6949:

This seems to have higher impact on performance than previously reported. I see many VersionProtocol methods use arrays as their input or output parameters, which can substantially benefit from this optimization.
See discussion started in HDFS-1583.
Reduces RPC packet size for primitive arrays, especially long[], which is used at block reporting

Key: HADOOP-6949
URL: https://issues.apache.org/jira/browse/HADOOP-6949
Project: Hadoop Common
Issue Type: Improvement
Components: io
Reporter: Navis
Priority: Trivial
Attachments: ObjectWritable.diff

Original Estimate: 0.17h
Remaining Estimate: 0.17h

Current implementation of oah.io.ObjectWritable marshals primitive array types as general object array ; array type string + array length + (element type string + value)*n
It would not be needed to specify each element types for primitive arrays.
