mysql - 配置单元 2.1.1 MetaException(消息 :Version information not found in metastore.)

Question

我在 Ubuntu 16.04 上运行 Hadoop 2.7.3、MySQL 5.7.17 和 Hive 2.1.1。

当我运行 ./hive 时，我不断收到以下警告和异常:

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/home/server/hive/lib/log4j-slf4j-impl-2.4.1.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/home/server/hadoop/share/hadoop/common/lib/slf4j-log4j12-1.7.10.jar!/org/slf4j/impl/StaticLoggerBinder.class]

这是我的 hive-site.xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
 <?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
 <configuration>

     <property>
         <name>javax.jdo.option.ConnectionURL</name>
         <value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true</value>
     </property>


     <property>
         <name>javax.jdo.option.ConnectionDriverName</name>
         <value>com.mysql.jdbc.Driver</value>

     <property>

     <property>
         <name>javax.jdo.option.ConnectionPassword</name>
         <value>password</value>
     </property>

 </configuration>

为了修复错误，我尝试了 Hive Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient和 Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient .但我仍然遇到相同的异常。

我是 Hadoop 和 Hive 的新手，我该如何修复异常？谢谢!

MySQL 中缺少 Metastore 所需的必要表。手动创建表并重新启动配置单元元存储。

MySQL 的模式文件将在路径 $HIVE_HOME/scripts/metastore/upgrade/mysql/ 下可用。

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;

重新启动 Hive 元存储。
