> 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.
