Assignee: Zoltán Borók-Nagy
> 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
> Assignee: Zoltán Borók-Nagy
> Priority: Major
>
> 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.
