Craig Macdonald updated PIG-112:
--------------------------------
Attachment: patch.import
initial patch for adding an import command to grunt.
This patch has a problem - I cant do any dump commands after applying the
patch, so I have probably broken something in PigScriptParser.jj
{code}
grunt> dump urls

Can someone give a look?

> Allow Java packages to be searched for functions.

> Key: PIG-112
> URL: https://issues.apache.org/jira/browse/PIG-112
> Project: Pig
> Issue Type: Improvement
> Reporter: Craig Macdonald
> Priority: Minor
> Attachments: patch.import
>
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> Motivation: Why should a user have to supply the fully qualified name to his
> user defined function, if all the functions he ever uses are in a pre-defined
> list of packages?
> Currently PigContext has a list of Java packages that are searched for
> functions. Currently the list consists of the following
> packages:
> * org.apache.pig.builtin.
> * org.apache.pig.impl.builtin.
> * com.yahoo.pig.yst.sds.ULT.
> Users should be able to add to this packagelist.
> Example in Grunt:
> {noformat}
> include com.pig.function.package.
> {noformat}
> This has connections to imports in Java classes, namespaces in XQuery, and
> the PATH env var in shell scripting.
> Should be trivial to implement, or could be a property.
