Alan Gates updated PIG-1881:

    Attachment: toolsserver.patch

This patch provides the requested interface.  It has gone out of sync with trunk (it's about
a month old now) and needs to be resynced.

>             Project: Pig
>          Issue Type: New Feature
>          Components: impl
>    Affects Versions: 0.9.0
>            Reporter: Alan Gates
>            Assignee: Laukik Chitnis
>            Priority: Minor
>             Fix For: 0.9.0
>         Attachments: toolsserver.patch
> The proposed Penny tool needs access to Pig's new logical plan in order to inject code
into the the dataflow.  Once it has modified the plan it needs to then be able to hand back
that modified plan and have Pig execute it.
> As we don't want to open this functionality up to general users, the proposal is to do
this by subclasses PigServer with a new class that is marked as LimitedPrivate for Penny only.
 This class will provide calls to parse a Pig Latin script and return a logical plan, and
one to take a logical plan and execute it.
