ORCFile 写入分区时需要使用内存进行写入 , 默认大小为256Kb , 需要通过调节alter table table_name set tblproperties("orc.compress.size"="65536") 来降低内存使用,我这里降低为原来的四分之一,进行参数调试

>alter table gdm.gdm_wt_minute set tblproperties("orc.compress.size"="65536")
-- 重跑SQL后无问题
>insert overwrite table xx.xxx_table_name partition(date) select * from xx.xxx_tmp_table;
