问题：获取组（合作伙伴， category , category2 )如果有重叠期

expected result: 

S1  01/12/2017  30/04/2018  c1  M
S1  01/01/2017  30/11/2017  c1  M
S1  01/02/2018  30/04/2018  c1  L
S2  01/02/2018  30/04/2018  c1  S
S3  01/12/2017  30/04/2018  c2  S

我的问题

SELECT DISTINCT partner, 
                category, 
                category2, 
                First_value(start_date) OVER (partition BY partner, category, category2 ORDER BY start_date) period_start,
                last_value(end_date) OVER (partition BY partner, category, category2 ORDER BY start_date rows BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED following) period_end
from (select pps.*, sum(start_new_period) over (partition BY partner, category, category2)
    FROM ( select partner, 
            start_date,
            end_date, 
            category, 
            category2, 
            lag(end_date) over (partition by partner, category, category2 order by start_date) previous_period_end
            , case 
                when start_date > lag(end_date) over (partition by partner, category, category2 order by start_date) 
                then 1 
                else 0 
                end start_new_period
            from big_hive_table
            where start_date is not null and end_date is not null) pps
)

当前，当我运行2个内部查询（从select pps.*）或整个查询时，出现以下错误：

Caused by: java.lang.RuntimeException: org.apache.hadoop.hive.ql.parse.SemanticException:Failed to breakup Windowing invocations into Groups. At least 1 group must only depend on input columns. Also check for circular dependencies.
Underlying error: Primitve type DATE not supported in Value Boundary expression

有人能告诉我我遗漏了什么吗。谢谢你的帮助。
