Ashish Thusoo commented on HADOOP-4070:
---------------------------------------

Looks good. Thanks for the contribution.
Only comment that I have is that in the patch you have duplicated the code for
compile-test in ql/build.xml
Would be better if instead we introduced a new target for building the udf jar
(on similar lines as gen-test) and have a dummy gen-test-jar in
build-common.xml which gets overwritten in ql/build.xml...
Its upto you if you want to incorporate that... But this is good as is...
Thanks again for the contribution... keep them rolling :)
