Subject [jira] Updated: (PIG-112) Allow Java packages to be searched for functions.
Date Mon, 18 Feb 2008 11:44:40 GMT

     [ https://issues.apache.org/jira/browse/PIG-112?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Craig Macdonald updated PIG-112:
--------------------------------

    Description: 
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.
