     [ https://issues.apache.org/jira/browse/PIG-1563?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dmitriy V. Ryaboy updated PIG-1563:
-----------------------------------

    Attachment: PIG_1563.patch

Updated the functions with the appropriate argToFunc mappings, added tests.
Also tried on current build of trunk to make sure all the up- and down- casting magic works, and it does.

Note the new methods in test.Utils and pig.impl.util.Utils -- pretty handy.
