We found that the test
[test_enable_reading_puffin()|https://github.com/apache/impala/blame/master/tests/custom_cluster/test_iceberg_with_puffin.py#L59]
added in IMPALA-13247 seems to fail in the Ozone build.

+*Stacktrace*+
{code}
custom_cluster/test_iceberg_with_puffin.py:50: in test_enable_reading_puffin
self._read_ndv_stats_expect_result([2, 2])
custom_cluster/test_iceberg_with_puffin.py:59: in _read_ndv_stats_expect_result
assert ndvs == expected_ndv_stats
E assert [-1, -1] == [2, 2]
E At index 0 diff: -1 != 2
E Full diff:
E - [-1, -1]
E + [2, 2]
{code}
According to the above, in the Ozone build, the result of "show column stats"
was [-1, -1]. It looks like the NDV statistics is not available in the Ozone
build.
