首先，hadoop集群已经安装好了，可以正常运行。
修改log4j文件 可选
cp hive-log4j.properties.template hive-log4j.properties
将EventCounter修改成org.apache.hadoop.log.metrics.EventCounter
#log4j.appender.EventCounter=org.apache.hadoop.hive.shims.HiveEventCounter
log4j.appender.EventCounter=org.apache.hadoop.log.metrics.EventCounter
配置元数据库
touch hive-site.xml
将以下信息写入到hive-site.xml文件中
<configuration>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://localhost:3306/hivedb?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>root</value>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>root</value>
</property>
</configuration>
5、安装mysql并配置hive数据库及权限
安装mysql数据库及客户端
yum install mysql-server
yum install mysql
service mysqld start
配置hive元数据库
mysql -u root -p
create database hivedb;
对hive元数据库进行赋权，开放远程连接，开放localhost连接
grant all privileges on *.* to root@"%" identified by "root" with grant option;
flush privileges;
6、运行hive命令即可启动hive
hive
附录1：如果报错Terminal initialization failed; falling back to unsupported
将/export/servers/hive/lib 里面的jline2.12替换了hadoop 中/export/servers/hadoop/hadoop-2.6.1/share/hadoop/yarn/lib/jline-0.09*.jar
附录2：jdbc驱动类 需要在hive的lib中添加mysql的连接驱动
附录3：异常信息
Logging initialized using configuration in jar:file:/export/servers/apache-hive-2.0.0-bin/lib/hive-common-2.0.0.jar!/hive-log4j2.properties
Exception in thread "main" java.lang.RuntimeException: Hive metastore database is not initialized. Please use schematool (e.g. ./schematool -initSchema -dbType ...) to create the schema. If needed, don't forget to include the option to auto-create the underlying database in your JDBC connection string (e.g. ?createDatabaseIfNotExist=true for mysql)
处理方法：
schematool -dbType mysql -initSchema
