错误： Key columns should be a ordered prefix of the schema.

解决：建表时UNIQUE KEY必须放在所有字段前面声明且保证有序
示例

drop TABLE `vhc_data_models`

CREATE TABLE IF NOT EXISTS `vhcDWH`.`vhc_data_models`
(
    `id` SMALLINT COMMENT "",
    `ton` VARCHAR(5) COMMENT "",
    `models` VARCHAR(30) COMMENT "",
    `vin` VARCHAR(20) COMMENT ""
) ENGINE = OLAP 
UNIQUE KEY(`id`)
DISTRIBUTED BY HASH
(
    `id`
) BUCKETS 1 
PROPERTIES
(
    "storage_type" =
    "COLUMN",
    "storage_medium" =
    "SSD",
    "storage_cooldown_time" =
    "2099-12-2 00:00:00",
    "replication_num" =
    "1"
);
show tables;
