[jira] Created: (PIG-183) Pig could not resolve my udf class
Pig could not resolve my udf class
----------------------------------
Key: PIG-183
URL: https://issues.apache.org/jira/browse/PIG-183
Project: Pig
Issue Type: Bug
Reporter: Xu Zhang
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';
{code}
{noformat}

My guess would be that your UDF.jar is not properly built.

[jira] Updated: (PIG-183) Pig could not resolve my udf class

------------------------
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:-

[jira] Commented: (PIG-183) Pig could not resolve my udf class
Posted by "Xu Zhang (JIRA)" <ji...@apache.org>.

Xu Zhang commented on PIG-183:
------------------------------
How so? As you can see from the attached testudf.jar, the StringStore class can be correctly found in the org.apache.pig.test.udf.storefunc package.
