Shubham Chopra commented on PIG-572:
------------------------------------

1. One use case is when users have a share-able script that does some preprocessing on data so users can then reuse it and build on it when using embedded pig. Its straight forward when using grunt, but not so much when using embedded pig. I'll ask Chris to point out any other use cases that he might have in mind.
2. This was for the example generator. I need a maping between logical operators and the generated examples. For cases where the grids are behind firewalls and can only be accessed through gateways, I need to run the example generator on the gateway and then serialize the maps to disk to get them to local machines. This needs the logical plan to be serializable.

> A PigServer.registerScript() method, which lets a client programmatically register a Pig Script.
> For example, say theres a script my_script.pig with the following content:
> a = load '/data/my_data.txt';
> b = filter a by $0 > '0';
> The function lets you use something like the following:
> pigServer.registerScript("my_script.pig");
> pigServer.registerQuery("c = foreach b generate $2, $3;");
> pigServer.store("c");
