> When I ran the following Pig script with the latest Pig stuff, I got an exception for
unresolved class. I noticed that org.apache.pig.test.udf.storefunc is not among the packages
that Pig searches ([, org.apache.pig.builtin., com.yahoo.pig.yst.sds.ULT., org.apache.pig.impl.builtin.]).

> I am sure that the package path for StringStore (org.apache.pig.test.udf.storefunc) is
correct in testudf.jar.  I attached testudf.jar here with this bug report.
