SQL：
[mw_shl_code=java,true]select start_date,count(1) num from tg_cdr_ims201708 group by start_date order by num[/mw_shl_code]

去看Hadoop下面看看log。猜测可能启用了Uber模式，最好关闭。

uber模式下mapreduce是在本地跑，reduce执行计划在hdfs上，本地获取不到执行计划报错关闭uber模式可以解决此问题
启动uber的情况下还有另一种解决方案：
hive-site.xml中配置下列属性
<property>
    <name>hive.rpc.query.plan</name>
    <value>true</value>
</property>
