["Santhosh Srinivasan (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PIG-158?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Santhosh Srinivasan updated PIG-158:
------------------------------------

    Attachment: udf_funcSpec.patch

The patch udf_funcSpec.patch does the following:

1. In LOUserFunc, funcSpec is passed instead of funcName
2. The translation from logical to physical layer uses the funcSpec instead of funcName
3. The parser looks for functions registered using registerFunction to retrieve the funcSpec
4. Changes to pigContext to support querying and instantiating functions registered using registerFunction
