Pi Song updated PIG-183:
------------------------
Attachment: pig_183_v1.patch
Mismatch java versions is something I also come across very often. I think the
real problem is that our code does swallow exception. Here is the patch that
exposes it as RuntimeException.
The new error message will look like this:-

>
> 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.
> {code}
> register /path/to/my/jar/testudf.jar;
> A = load '/user/pig/tests/data/singlefile/textdoc' using
> org.apache.pig.test.udf.storefunc.StringStore();
> store A into 'results_4_1';
