> Key: PIG-1337

> Project: Pig
> Issue Type: Improvement
> Affects Versions: 0.6.0
> Reporter: Chao Wang
>
> The Zebra storage layer needs to use distributed cache to reduce name node
> load during job runs.
> To to this, Zebra needs to set up distributed cache related configuration
> information in TableLoader (which extends Pig's LoadFunc) .
> It is doing this within getSchema(conf). The problem is that the conf object
> here is not the one that is being serialized to map/reduce backend. As such,
> the distributed cache is not set up properly.
> To work over this problem, we need Pig in its LoadFunc to ensure a way that
> we can use to set up distributed cache information in a conf object, and this
> conf object is the one used by map/reduce backend.
