内部加入Hive生成IndexOutOfBound错误

Question

我有两张桌子，我正试图join与

drop table if exists test.thing_bid;

create table if not exists test.thing_bid as
select
    pq.nr,
    pq.id_l,
    sna.id_c,
    sna.num_total,
    pq.ref_month
from
    stage.sna sna
join
    stage.snapshot_monthly pq
on
    (pq.nr = sna.ph and pq.ref_month = sna.ref_month)

但我收到了错误

Error: Error while compiling statement: FAILED: IndexOutOfBoundsException Index: 0, Size: 0 (state=42000,code=40000)

这不是很有帮助。每个表的字段类型相同。为什么会出现此错误？
