[jira] [Created] (IMPALA-11771) Support native udf for codegen cache

Yida Wu created IMPALA-11771:
--------------------------------

             Summary: Support native udf for codegen cache
                 Key: IMPALA-11771
                 URL: https://issues.apache.org/jira/browse/IMPALA-11771
             Project: IMPALA
          Issue Type: Improvement
            Reporter: Yida Wu
            Assignee: Yida Wu


As a follow-up task of IMPALA-11470,  reusing a native udf from a codegen cache  entry could lead to a crash because the cached function could point to an invalid address when the udf is recreated in runtime. So IMPALA-11470 disables the codegen cache for a fragment with any native udf.
