I'm afraid I'm out of my depth now, as I don't know anything about the Python implementation of Avro. Perhaps someone else can help. Or if you think it's a bug, please post a reproducible test case on https://issues.apache.org/jira/browse/AVRO

So I installed snappy and python-snappy and avro via pip as per https://github.com/phunt/avro-rpc-quickstart When I tried to run the start_server.py<https://github.com/phunt/avro-rpc-quickstart/tree/master/src/main/python>, I get the following error: python $ ./start_server.py Traceback (most recent call last): File "./start_server.py", line 20, in <module> import avro.ipc as ipc File "build/bdist.macosx-10.8-intel/egg/avro/ipc.py", line 35, in <module> File "build/bdist.macosx-10.8-intel/egg/avro/schema.py", line 778, in parse avro.schema.SchemaParseException: Error parsing JSON: @HANDSHAKE_REQUEST_SCHEMA@ python $ Thanks, Lenin On Sat, Apr 5, 2014 at 12:47 AM, Martin Kleppmann <mkleppm...@linkedin.com<mailto:mkleppm...@linkedin.com>> wrote: Try installing Homebrew (http://brew.sh/) and then doing `brew install snappy`. That will put libsnappy in /usr/local/lib.

But to use the python server, I need to install "libsnappy-dev" in Mac OS as per https://github.com/phunt/avro-rpc-quickstart. Do you know how to install this library in Mac OS? or is there an alternate way to setup a python RPC server using Avro?

If you can live with yajl for now, 1.7.5 should work fine for you.

Went to lang/ruby/ and modified Rakefile as: p.runtime_dependencies = %w[multi-json] to p.runtime_dependencies = %w[multi_json] and `sudo rake install` I am able to do RPC using Ruby server/client. I want a python server actually. In the repo https://github.com/phunt/avro-rpc-quickstart, there is lib named "libsnappy-dev". Does anybody know its equivalent for Mac OS?

(Gem::UnsatisfiableDependencyError) Unable to resolve dependency: avro (= 1.7.6) requires multi-json (>= 0) I learnt that, this was fixed in 1.7.7 (https://issues.apache.org/jira/browse/AVRO-1459) but the gem page(http://rubygems.org/gems/avro) still shows 1.7.6. When do we get the latest version? or How can build the gem locally by applying the patch? Thanks, Lenin
