[jira] [Commented] (MAPREDUCE-377) Add serialization for Protocol Buffers

["Pere Ferrera Bertran (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAPREDUCE-377?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13081031#comment-13081031 ] 

Pere Ferrera Bertran commented on MAPREDUCE-377:
------------------------------------------------

PB integration with Hadoop is now possible by using Protostuff (http://code.google.com/p/protostuff/) by calling ProtobufIOUtil.writeDelimitedTo() and ProtobufIOUtil.mergeDelimitedFrom() . These methods avoid the problem with consuming too many bytes from the stream.

> Protocol Buffers (http://code.google.com/p/protobuf/) are a way of encoding data in a compact binary format. This issue is to write a ProtocolBuffersSerialization to support using Protocol Buffers types in MapReduce programs, including an example program. This should probably go into contrib.
