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}
