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