Hive store all the data without partition columns to a default partition named __HIVE_DEFAULT_PARTITION__. Doris will fail to get the this partition when the partition column type is INT or something else that __HIVE_DEFAULT_PARTITION__ couldn't convert to. This pr is to support hive default partition, set the column value to NULL for the missing partition columns.
