Mark Van De vyver commented on HADOOP-3787:
-------------------------------------------
I've seen several list discussions/mentions of Thrift and serialization, but
have not seen extprot yet mentioned. It is recent, but relevant to this issue
(and in its own right):
http://eigenclass.org/R2/writings/extprot-extensible-protocols-intro
and
http://eigenclass.org/R2/writings/protocol-extension-with-extprot
<quote>
At this point, you'll be thinking, "what, yet another Protocol
Buffers/Thrift/ASN.1 DER/XDR/IIOP/IFF?"... Not quite: extprot differentiates
itself in that it allows for more extensions and supports richer types (mainly
tuples and disjoint union types aka. sum types) than Protocol Buffers or Thrift
without approaching the complexity of ASN.1 DER. (Note that XDR does not define
self-describing protocols, making protocol changes hard at best.)

> Add serialization for Thrift

> Key: HADOOP-3787

>
> Thrift (http://incubator.apache.org/thrift/) is cross-language serialization
> and RPC framework. This issue is to write a ThriftSerialization to support
> using Thrift types in MapReduce programs, including an example program. This
> should probably go into contrib.
> (There is a prototype implementation in
> https://issues.apache.org/jira/secure/attachment/12370464/hadoop-serializer-v2.tar.gz)
