RE: Getting sys.argv using embedded jython
Duckworth, Will 2012-06-18, 21:52
I tried a couple other versions.

This will work:

#!/usr/bin/python

import sys

from org.apache.pig.scripting import Pig

if __name__ == '__main__':
    print sys.argv[1]
This will not:

#!/usr/bin/python

import sys

from org.apache.pig.scripting import Pig

@outputSchema("ip_address:long")
def Ip2Num(ip):
    pass

if __name__ == '__main__':
    print sys.argv[1]

This has to be something obvious but I can’t seem to get python parameters once I add in a main().  Thanks.
