这是我的 hive-site.xml
Here is my hive-site.xml

为了修复错误，我尝试了 Hive 无法实例化 org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient 和 无法实例化 org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient.但我仍然遇到相同的例外情况.
In order to fix the error, I've tried Hive Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient and Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient. But I am still getting the same exceptions.
我是 Hadoop 和 Hive 的新手，我该如何修复异常?谢谢！
I'm newbie to Hadoop and Hive, how could I fix the exception? Thanks!
在 MySQL 中缺少 Metastore 所需的必要表.手动创建表并重新启动 hive Metastore.
The necessary tables required for the metastore are missing in MySQL. Manually create the tables and restart hive metastore.
MySQL 的模式文件将在路径 $HIVE_HOME/scripts/metastore/upgrade/mysql/ 下可用.
The schema files for MySQL will be available under the path $HIVE_HOME/scripts/metastore/upgrade/mysql/.
cd $HIVE_HOME/scripts/metastore/upgrade/mysql/
< Login into MySQL >
mysql> drop database IF EXISTS hive;
mysql> create database hive;
mysql> use hive;
mysql> source hive-schema-2.1.1.mysql.sql;
重启 Hive Metastore.
Restart Hive metastore.
