一、复制Hadoop配置文件（core-site.xml，hdfs-site.xml，hive-site.xml）到Spark的conf下
二、复制Hive的mysql-connector-java-5.1.40-bin.jar到Spark的jars中
三、 启动Spark下的Thriftserver服务
sbin/start-thriftserver.sh \
--master local[*] \
--hiveconf hive.server2.thrift.port=16000四、使用Spark下的beeline链接
bin/beeline -u jdbc:hive2://hdp5:16000 -n hadoop五、SQL性能测试（Spark明显比Tez还要快两倍多）
六、可能遇到的问题

<property>
<name>hive.metastore.schema.verification</name>
<value>false</value>
</property>七、总结
整合的过程需要注意的地方是，从Spark 1.4.0开始，内部Spark SQL将针对Hive 1.2.1进行编译，可以使用单个Spark SQL二进制构建来查询不同版本的Hive metastore，所以在切换到SparkSQL的同时Hive的元数据信息也会被修改。
