Have you seen the Erlang project?
http://www.erlang.org/about.html
It seems interesting to me. And, I'm think about erlang interface to
hadoop/hama.
Has anyone considered doing this?

Another interesting development in Erlang is something called Scalaris.
(http://www.onscale.de/scalaris.html ) which is a distributed key-store
thing.

Hmm... I see.

I have some examples. Like RabbitMQ is a message-oriented system, it's
implemented in Erlang and throughput is really good (according to its
web site). Another example is Yawn, an HTTP server written in Erlang
as well. It can be handling a number of concurrent connections more
than Apache.
So the nature of Erlang is for writing highly scalable servers, and we
need a simpler programming model (C/Java/Ruby/Groovy) as the front
APIs.
Not sure if this can answer your question.

Erlang is good for highly massive parallel system, which is suitable
for implementing backend.
It's alright if you're going to rewrite Hadoop using Erlang, but it's
not fit for Erlang to be a a front layer, AFAIK.

Great!!
BTW, This is some opinion from the hama mailing list.

Its an interesting language for coding in, very prology, string handling
is almost worst than C, but it has good parallel and functional coding
features. I'm doing some spare time erlangy stuff, and I have colleagues
that have stopped saying "Ruby is the future" and now say "Erlang is the
future".
> Has anyone considered doing this?
In Apache, CouchDB is built on Erlang; there's also a MR framework from
Nokia (Disco?) that is now OSS. Also, check out ErlyBird for doing
Erlang coding.
