Alan Gates updated PIG-928:
---------------------------
Attachment: package.zip
Attaching some preliminary work by Kishore Gopalakrishna on this. This code is
a good start, but not ready for inclusion. It needs to be cleaned up, put in
our class structure, etc.
Comments from Kishore:
It contains all the libraries required and also the GenericEval UDF and
GenericFilter UDF
I dint get a chance to get the Algebraic function working.
To test it, just unzip the package and run
rm -rf wordcount/output;
pig -x local wordcount.pig ---> to test eval
pig -x local wordcount_filter.pig ---> to test filter [sorry it should
be named filter.pig]
cat wordcount/output
> UDFs in scripting languages

> It should be possible to write UDFs in scripting languages such as python,
> ruby, etc. This frees users from needing to compile Java, generate a jar,
> etc. It also opens Pig to programmers who prefer scripting languages over
> Java.
