------------------------------------------
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.
