Hive错误：编译语句时出错：FAILED：ParseException 3:47缺失：在'<eof>'附近的'array'处

Question

我想在结构中创建结构数组。

CREATE EXTERNAL TABLE TEST_EXTTBL_PAGE_VISIT_MASTER
(
    PERSONALIZATION_DATA STRUCT<EXPOSED_RULES array<struct<RULE_ID:varchar(70),RULESETID:varchar(70)>>>
)
COMMENT 'Page Visit details'
row format delimited fields terminated by ','
collection items terminated by '|'
map keys terminated by ':'
lines terminated by '\n'
LOCATION 's3a://XXX';

请提出我在这里遗失的内容。

(
    PERSONALIZATION_DATA STRUCT<EXPOSED_RULES: array<struct<RULE_ID:varchar(70),RULESETID:varchar(70)>>>
)
COMMENT 'Page Visit details'
row format delimited fields terminated by ','
collection items terminated by '|'
map keys terminated by ':'
lines terminated by '\n'
LOCATION 's3a://XXX';
