------------------------------------
Hello Julien,
I have a question about this jira.
I've been reading Pig UDF code to understand why I need different DEFINEs in
order to pass different constructor parameters to the AvroStorage constructor.
What I found is that aliases are mapped with FuncSpec instances that store not
only function names but also args specified in DEFINE statements. Later when
aliases are expanded by LogicalPlanBuilder, function objects are instantiated
from those FuncSpec instances, resulting that args specified in DEFINE
statements are used to instantiate function objects instead of ones specified
in LOAD statements.
My question is whether this jira is to solve the same problem or not. I am a
bit confused because the title says "scripting UDFs", but I thought that
scripting UDFs are EvalFuncs, and EvalFuncs take no parameters in their
constructors. Please forgive me if I am misunderstanding something here. I am
still learning Pig internal.
Thanks!
