Description

With Iceberg 0.13 the Table serialization has been changed, a new class was added SerializableTable, that causes ClassCastException when using the newer Iceberg library.

E    MESSAGE: AnalysisException: org.apache.impala.catalog.TableLoadingException: Error opening Iceberg table 'iceberg_insert_event_db_cmenn.ice_test'
E   CAUSED BY: TableLoadingException: Error opening Iceberg table 'iceberg_insert_event_db_cmenn.ice_test'
E   CAUSED BY: ClassCastException: org.apache.iceberg.SerializableTable cannot be cast to org.apache.iceberg.BaseTable

The new approach is to use the SerializableTable class when serializing table, this is a lightweight Table class, however to keep Impala cross compatible between libraries we should remove the Iceberg's Table object serialization for now.
