--------------------------


> 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: import.v2.patch, import.v3.patch, 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.
