------------------------------------
I integrated the latest patch and run unit tests. All the AVRO unit tests
failed with the following stack trace:
Could not initialize class

> Use Avro serialization in Pig
> -----------------------------
>
> Key: PIG-794
> URL: https://issues.apache.org/jira/browse/PIG-794
> Project: Pig
> Issue Type: Improvement
> Components: impl
> Affects Versions: 0.2.0
> Reporter: Rakesh Setty
> Fix For: 0.2.0
>
> Attachments: avro-0.1-dev-java.jar, AvroStorage.patch,
> jackson-asl-0.9.4.jar
>
>
> We would like to use Avro serialization in Pig to pass data between MR jobs
> instead of the current BinStorage. Attached is an implementation of
> AvroBinStorage which performs significantly better compared to BinStorage on
> our benchmarks.
