解决方法
explain这个sql

Access Path:
+-JOIN MERGEJOIN(inputs presorted) [Cost: 815, Rows: 10K (NO STATISTICS)] (PATH ID: 1)

注意这里NO STATISTICS是没用收集统计信息
没用收集统计信息导致sql占用内存超过既定内存，从而导致上述报错
select ANALYZE_STATISTICS('web.jslogrecord')
select ANALYZE_STATISTICS('web_test.Dim_Ip_Borui')
select ANALYZE_STATISTICS('web_test.web_dim_domain')
select ANALYZE_STATISTICS('common.Cmm_Dim_Geography')
select ANALYZE_STATISTICS('web.Web_Dim_Time')
只需收集全部统计信息即可解决
