昨天还好好的，今天问题突然变成这样子了

lcc@lcc ~$ hive --service metastore

这个问题是版本号冲突导致的

2.解决方法（测试可用）

2.1 解决方法1：修改版本号

查看mysql，可以看到这里是

可以在这里直接修改

然后直接重启服务，正常了

lcc@lcc ~$ hive --service metastore

命令修改

1.登陆mysql，修改hive metastore版本：
进行mysql：mysql -uroot -p （123456）
use hive;
select * from version;
update VERSION set SCHEMA_VERSION='2.1.1' where  VER_ID=1;

2.2 解决方法2：关闭版本验证

简单粗暴：在hvie-site.xml中关闭版本验证

<property>
    <name>hive.metastore.schema.verification</name>
    <value>false</value>
</property>
