Major Description
For Kudu tables created through Impala, we store a tblproperty called 'kudu.num_tablet_replicas', indicating the replication factor for the table.
If this value is set in a create table, it is passed to Kudu and actually applied to the table. However, altering this property is allowed but has no effect on the underlying table, which could be confusing.
We should either disallow altering the property, or we should pass the new value down to Kudu (if Kudu allows changing the replication factor after table creation)
