Need a special interface for Penny (Inspector Gadget)
-----------------------------------------------------
Key: PIG-1881
URL: https://issues.apache.org/jira/browse/PIG-1881
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
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.
