[jira] Created: (PIG-863) Function (UDF) automatic namespace
resolution is really needed
Function (UDF) automatic namespace resolution is really needed
--------------------------------------------------------------
Key: PIG-863
URL: https://issues.apache.org/jira/browse/PIG-863
Project: Pig
Issue Type: Improvement
Reporter: David Ciemiewicz
The Apache PiggyBank documentation says that to reference a function, I need to specify a function as:
org.apache.pig.piggybank.evaluation.string.UPPER(text)
As in the example:
{code}
REGISTER /public/share/pig/contrib/piggybank/java/piggybank.jar ;
TweetsInaug = FILTER Tweets BY org.apache.pig.piggybank.evaluation.string.UPPER(text) MATCHES '.*(INAUG|OBAMA|BIDEN|CHENEY|BUSH).*' ;
{code}
Why can't we implement automatic name space resolution as so we can just reference UPPER without namespace qualifiers?
{code}
REGISTER /public/share/pig/contrib/piggybank/java/piggybank.jar ;
TweetsInaug = FILTER Tweets BY UPPER(text) MATCHES '.*(INAUG|OBAMA|BIDEN|CHENEY|BUSH).*' ;
{code}
I know about the workaround:
{code}
define org.apache.pig.piggybank.evaluation.string.UPPER UPPER
{code}
But this is really a pain to do if I have lots of functions.
Just warn if there is a collision and suggest I use the "define" workaround in the warning messages.

See related JIRA PIG-112 although I think this one is slightly different.
