             Summary: Impala crashes on old Iceberg table property in some cases
                 Key: IMPALA-10935
                 URL: https://issues.apache.org/jira/browse/IMPALA-10935
             Project: IMPALA
          Issue Type: Bug
            Reporter: Zoltán Borók-Nagy


Impala crashes when the following conditions are true:

* local catalog mode is being used
* Iceberg table is being queried
* 'iceberg.file_format' is set instead of 'write.format.default' table property
* the file format is ORC
* Query is select count(*) from t;

When the above conditions met Impala wrongly assumes that PARQUET is being used and tries to apply the count star optimization. It is not implemented for the ORC scanner and causes it to crash.
