Date Wed, 19 Oct 2011 09:35:53 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The "ProtocolBuffers" page has been changed by SteveLoughran:
http://wiki.apache.org/hadoop/ProtocolBuffers?action=diff&rev1=1&rev2=2

  
  !ProtocolBuffers is an open source project supporting Google's !ProtocolBuffer's platform-neutral
and language-neutral interprocess-communication (IPC) and serialization framework. It has
an Interface Definition Language (IDL) that is used to describe the wire- and file formats;
this IDL is then pre-compiled into source code for the target languages (Python, Java and
C++ included), which are then used in the applications.
  
- Hadoop 0.23+ requires the protocol buffers JAR to be on the classpath of both clients and
servers; the native binaries are required to compile this and later versions of Hadoop.
+ Hadoop 0.23+ requires the protocol buffers JAR (protobufs.jar) to be on the classpath of

  In comparison with previous IDLs (such as CORBA, DCOM and !SunOS RPC), !ProtocolBuffers
are designed to be
   * Simple remote procedure calls (not Object-Oriented communication in the style of CORBA).
