[jira] [Created] (IMPALA-15399) Calcite planner: NULL * NULL datatype doesn't match

Steve Carlin created IMPALA-15399:
-------------------------------------

             Summary: Calcite planner: NULL * NULL datatype doesn't match
                 Key: IMPALA-15399
                 URL: https://issues.apache.org/jira/browse/IMPALA-15399
             Project: IMPALA
          Issue Type: Bug
            Reporter: Steve Carlin


The exprs-test.cc file has some tests that are not in the e2e tests.

One of them is testing the datatype returned by "NULL * NULL". 

The original planner returns DOUBLE whereas the Calcite Planner returns null.

The expr-test file isn't completely working yet, but this can be replicated by creating a "select NULL * NULL" test within a ".test" file
