I'm running Hadoop 2.7.3, MySQL 5.7.17 and Hive 2.1.1 on Ubuntu 16.04.

当我运行 ./hive 时，我不断收到以下警告和异常:

When I run ./hive, I keep getting the following warning and exception:

这是我的 hive-site.xml

Here is my 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.ConnectionUserName</name>
         <value>hive</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 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!

推荐答案

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.
