Woody Anderson commented on PIG-1824:
-------------------------------------
1. i could re-work the initialization into the static block of the inner class
"Interpreter", it simply needs to be done before the interpreter is allocated.
I'm not sure what you mean by not wanting a cache dir when using python udfs or
control flow? can you clarify?
2. separate the logic out of init into what? I think it should, in general, be
the contract of any script environment to handle resource inclusion (if
possible). Are you imagining some scenario where init(file,..) would not
actually parse/internalize the code inside init()? I don't much care where the
code is parsed and added to a ScriptEngine, but when it is, it should handle
all other evaluated resources that are necessary to succeed. In the current
API, a user provided script file is given to init(), so that's where it must do
this. There is really no other place to evaluate resource inclusions, and i
think i might not be understanding your suggestion. As for other ScriptEngines
that may not be able to support this concept, are you suggesting a
"supportsFeature()" method that we use to test various SE's to determine if
they can support this (or other) features? I'm not sure what we'd do with this
knowledge.

> Project: Pig
> Issue Type: Improvement
> Affects Versions: 0.8.0, 0.9.0
> Reporter: Richard Ding
> Assignee: Woody Anderson
> Fix For: 0.9.0
>
> Attachments: 1824.patch, 1824a.patch

>
> Currently, Jython UDF script doesn't support Jython import statement as in
> the following example:
> {code}
> #!/usr/bin/python
> import re
> @outputSchema("word:chararray")
> def resplit(content, regex, index):
> return re.compile(regex).split(content)[index]
> {code}
> Can Pig automatically locate the Jython module file and ship it to the
> backend? Or should we add a ship clause to let user explicitly specify the
> module to ship?
