PS3, Line 571:         List<? extends FeFsPartition> partitions = new 
ArrayList<>(fsTable.loadAllPartitions());
             :         partitions.sort(HdfsPartition.KV_COMPARATOR);
             :         for (FeFsPartition p : partitions) {
This can have potential scale issue if a table has thousands of partitions, 
potentially blowing up CatalogD or local catalog.
I recommend skipping the per-partition ALTER for now, just to be safe.

             :   def test_show_create_table_with_stats_matrix(self, vector, 
unique_database, cfg, fmt):
Is it possible to follow existing tests in using 
__run_show_create_table_test_case and .test file?
See 
./testdata/workloads/functional-query/queries/QueryTest/show-create-table.test 
for example.
