------------------------------------------
Summary: Make sure Impala returns error for Iceberg tables with
equality deletes
Key: IMPALA-11964
URL: https://issues.apache.org/jira/browse/IMPALA-11964
Project: IMPALA
Issue Type: Bug
Components: Frontend
Reporter: Zoltán Borók-Nagy
Impala only supports position deletes currently.
It should raise an error when equality deletes are encountered:
[https://github.com/apache/impala/blob/eaf71bca0a3538056765dbbce13c0f503045b38b/fe/src/main/java/org/apache/impala/planner/IcebergScanPlanner.java#L344]
But if we are not invoking planFiles() it's possible that Impala starts reading
equality delete files as position delete files which should also raise an
error. But it would be still better to catch the error during planning.
To make sure we should add tests for these scenarios.
