Description

HCatalog's pig support should be moved into a separate jar.

DETAILS:

One of HCatalog's major goals is making the HiveMetaStore accessible to other processing frameworks (pig for example). If we bundle everything inside a single hcatalog.jar it will have a large number of processing framework dependencies.

For example, let's say HCatalog has the core classes, and adaptors for pig & scalding all bundled inside a single hcatalog.jar. The maven dependencies will include both pig & scalding. Projects integrating with hcat either end up with way more dependencies than necessary, or they need to pick & choose which dependencies to include in their project.

Packaging pig support as a separate jar allows users to get the pig support without dependencies from other processing frameworks.
