Description
in hive-0.13.1, the map datatype column from hcatalog has output order different from the hive output order. But Struct time is fine. And this behavior also can be found in Text file format, not just in RC file format.
This is caused by the changes in this patch HIVE-7282.
This patch of HIVE-7282 should not go into Hive 0.13.1 unless it has a better way to preserve the order of key-value pairs.
