[jira] [Updated] (PIG-1824) Support import modules in Jython UDF

["Woody Anderson (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PIG-1824?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Woody Anderson updated PIG-1824:
--------------------------------

    Description: 
Currently, Jython UDF script doesn't support Jython import statement as in the following example:

{code}
#!/usr/bin/python

import re
@outputSchema("word:chararray")
def resplit(content, regex, index):
        return re.compile(regex).split(content)[index]
{code}

Can Pig automatically locate the Jython module file and ship it to the backend? Or should we add a ship clause to let user explicitly specify the module to ship?
