----------------------------------
Summary: Refactor XDR code into XDRReader and XDRWriter
Key: HADOOP-9966
URL: https://issues.apache.org/jira/browse/HADOOP-9966
Project: Hadoop Common
Issue Type: Improvement
Reporter: Haohui Mai
Assignee: Haohui Mai
Several methods in the current XDR class have ambiguous semantics. For example,
Size() returns the actual size of internal byte array. The actual size of
current buffer, is also affected by read requests, which pull data out of the
buffer.
These ambiguous semantics makes removing redundant copies on the NFS paths
difficult.
This JIRA proposes to decompose the responsibilities of XDR into two separate
class: XDRReader and XDRWriter. The overall designs should closely follow
Java's *Reader / *Writer classes.
