我的问题是

SELECT txnno, product FROM txnrecsbycat TABLESAMPLE(BUCKET 2 OUT OF 10) ORDER BY txnno;

我正在获得成功，但无法查看我的o/p我的o/p是：
total jobs=1启动job 1（共1个）编译时确定的reduce任务数：1为了更改reducer的平均负载（以字节为单位）：

set hive.exec.reducers.bytes.per.reducer=<number>

为了限制减速器的最大数量：

set hive.exec.reducers.max=<number>

为了设置恒定数量的减速器：

set mapreduce.job.reduces=<number>
