执行hive sql的时候
hive> select * from records r join records2 r2 on r.year=r2.year join records3 r3 on r3.year=r2.year;
Total MapReduce jobs = 1

Number of reduce tasks not specified. Estimated from input data size: 1
In order to change the average load for a reducer (in bytes):
set hive.exec.reducers.bytes.per.reducer=<number>
In order to limit the maximum number of reducers:
set hive.exec.reducers.max=<number>
In order to set a constant number of reducers:
set mapred.reduce.tasks=<number>

引用 6 楼 ys198519 的回复:
我也遇到这问题了,8亿条记录,插入1个表,报这个错误。我改为分3批插入,就没问题了。
哦,听起来你的问题是因为数据量大的问题导致的?我这个并不是啊,只有很少的数据 就10多条而已。
