简单查询，例如select，工作正常，但是当我使用聚合函数时，例如count，我遇到了错误。
我使用beeline通过Spark 2.2.0和Hadoop 2.8连接到Hive 2.1.1。
hive-site.xml如下：
<property>
<name>hive.execution.engine</name>
<value>spark</value>
<description>
Expects one of [mr, tez, spark].
Chooses execution engine. Options are: mr (Map reduce, default), tez, spark. While MR
remains the default engine for historical reasons, it is itself a historical engine
and is deprecated in Hive 2 line. It may be removed without further warning.

在配置单元中执行select count(*) from table时，我收到以下错误：
