Review comment:
Example usecase:
There is a location where a external system is writing files every day.
An external partitioned Hive table is created on top of the location,
partitioned on day.
Once the external table is created, we need to run "ALTER TABLE RECOVER
PARTITIONS" or "MSCK REPAIR TABLE" to register the partitions in metastore. .
When we dont recover(register against metastore) a partitions(intentionally
or unintentionally), the data corresponding to unrecovered partition is not
returned as part of the table scan.
This test checks if both Spark and Iceberg returns same data, when there are
unrecovered partitions
