Attachment: PIG-1125.patch
> [zebra] Using typed APIs for Zebra's Map/Reduce interface
> ---------------------------------------------------------
>
> Key: PIG-1125
> URL: https://issues.apache.org/jira/browse/PIG-1125
> Project: Pig
> Issue Type: Improvement
> Affects Versions: 0.4.0
> Reporter: Chao Wang
> Assignee: Chao Wang
> Fix For: 0.6.0, 0.7.0
>
> Attachments: PIG-1125.patch

>
> We plan to modify Zebra's M/R interface to use typed APIs, i.e., APIs taking
> object arguments, instead of String arguments.
> Take TableInputFormat as an example:
> setSchema(jobConf conf, String schema) is changing to setSchema(jobConf conf,
> ZebraSchemaInfo schemaInfo)
> setProjection(jobConf conf, String projection) is changing to
> setProjection(jobConf conf, ZebraProjectionInfo projectionInfo)
> and so on.
> Benefits: 1) Typed APIs make it easier to detect usage mistakes earlier and
> 2) Typed APIs are richer and hide things better.
> In the meanwhile, we plan to make the old APIs deprecated, instead of
> removing them, for the sake of safety.
