HiveMetaStore里面记录的Hive版本一致，我们可以通过配置
hive.metastore.schema.verification参数来取消这种验证，这个参数的默认值是true，我们可以取消验证，配置如下：
<property> <name>hive.metastore.schema.verification</name> <value>false</value> <description> Enforce metastore schema version consistency. True: Verify that version information stored in metastore matches with one from Hive jars. Also disable automatic schema migration attempt. Users are required to manully migrate schema after Hive upgrade which ensures proper metastore schema migration. (Default) False: Warn if the version information stored in metastore doesn't match with one from in Hive jars. </description> </property>
然后我们再启动Spark，这时候就可以创建SQLContext实例了。
