hive 不能使用mapreduce进行查询? 10C

hadoop版本:chd5.1.0
hive版本:hive0.12-chd5.1.0
web页面:hadoop,yarn都正常启动,页面监控正常
hive我做测试用,使用的是默认的derby数据库,hive-env.sh,配置了hadoop的路径,
hive-site.xml使用默认的,没有做任何修改
接着做简单的测试:

hive> select count(*)from hive_sum;
Total MapReduce jobs = 1
Launching Job 1 out of 1
Number of reduce tasks determined at compile time: 1
In order to change the average load for a reducer (in bytes):
set hive.exec.reducers.bytes.per.reducer=
In order to limit the maximum number of reducers:
set hive.exec.reducers.max=
In order to set a constant number of reducers:
set mapred.reduce.tasks=
