--------------------------------
Summary: Introduce RPCInfo to decouple XDR classes from the RPC API
Key: HDFS-5230
URL: https://issues.apache.org/jira/browse/HDFS-5230
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Haohui Mai
Assignee: Haohui Mai
The XDR class is one fundamental aspect in the current implementation of NFS
server. While the client might potentially have a higher level APIs, it also
requires redundant copying since the upstream clients have insufficient
information.
This JIRA introduces a new class, RPCInfo, which (1) decouples XDR from the
APIs, turning it into a utility class, and (2) exposes ChannelBuffer directly
to the client in order to open the opportunity for avoid copying.
