Hive的Metastore contains multiple versions

hive 客户端报错：Exception in thread "main" java.lang.RuntimeException: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient

咋一看以为是Mysql连接不上，结果发现Mysql正常

错误日志：

解决方案：

 1 mysql> select * from version;

原因暂且未知，不过我记得我当时是打开了Hive客户端，但是网络突然断了，不知道是否是这个原因。
