   For any future readers, this is unpatchable on Spark 3.0 (3.1 + are fine once the above pr is merged). The underlying issue there is prior to [SPARK-32990](https://issues.apache.org/jira/browse/SPARK-32990) the V1 SparkSession catalog refresh method is called whenever `REFRESH TABLE` is invoked. This means we can't change the behavior of the refresh table command. A workaround is too instead use ```cloneSession()``` on  the `SparkSession` class and discard the previous session. This will recreate the catalog and pick up new Iceberg Table changes.
