[jira] [Created] (IMPALA-11710) Table properties are not updated in Iceberg metadata files

Noemi Pap-Takacs created IMPALA-11710:
-----------------------------------------

             Summary: Table properties are not updated in Iceberg metadata files
                 Key: IMPALA-11710
                 URL: https://issues.apache.org/jira/browse/IMPALA-11710
             Project: IMPALA
          Issue Type: Bug
            Reporter: Noemi Pap-Takacs


Iceberg stores the default file format in a table property called 'write.format.default'.  HMS also stores this value loaded from the Iceberg metadata json file.

However, when this table property is altered through Impala, it is only changed in HMS, but does not update the Iceberg snapshot. When the table data is reloaded from Iceberg metadata, the old value will appear in HMS and the change is lost.

This bug does not affect table properties that are not stored in Iceberg, because they will not be reloaded.
