-------------------------------------
Summary: UDF/UDA samples should explicitly export entry points
Key: IMPALA-8187
URL: https://issues.apache.org/jira/browse/IMPALA-8187
Project: IMPALA
Issue Type: Improvement
Components: Backend
Reporter: Tim Armstrong
Assignee: Tim Armstrong
It's possible for UDF authors to get into a pickle by exporting symbols from
UDF/UDA shared objects unintentionally. E.g. if using boost headers, which
result in weak symbols in the .so, which then get merged with the
(incompatible) symbols in the impalad binary.
We should really be keeping symbols hidden by default then exporting the entry
points explicitly in the UDF/UDA code
