Hi all,
I am trying to add my own UDFs and rebuild the hive package. Actually I add the UDFs successfully and pass the build stage and get the new-release, but I can't get the correct result from calling "show functions" on hive cli. I read the article https://cwiki.apache.org/confluence/display/Hive/GenericUDAFCaseStudy carefully and added udf_myfunc.q and udf_myfunc.q.out, however when I  run the test of "ant test -Dtestcase=TestCliDriver -Dqfile=show_functions.q -Doverwrite=true" I got the following error message.
