Can't we just change the built-in CONCAT to accept additional fields?
This would be totally backward compatible. I know it won't help now.

The CONCAT in the oink project (LinkedIn's UDFs) does concatenation of
any number of string arguments:

We're going to merge this with elephant-bird when we get a chance, and
this UDF could use a new name like MULTI_CONCAT, but it should work
for you.

Hello,
I am trying to create a full address and full location field in Pig
by combining multiple fields.
file = LOAD 'file.txt' USING PigStorage() AS
(house:chararray,
predir:chararray,
street:chararray,
streettype:chararray,
postdir:chararray
city:chararray,
state:chararray,
zip:chararray)
I need an output that is full address and full location:
full_address == house + ' ' + predir + ' ' + street + ' ' +
streettype + ' ' + postdir
full_location == city + ' ' + state + ' ' + zip
I can get two to merge with CONCAT using but am not able to add
more or the spaces in between.
Temp1 = FOREACH file GENERATE CONCAT (house,street)
Any ideas?
Thanks
Scott
