修改hive-site.xml，将value修改為false即可！

<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.
