Hive安装，

Hive安装，

hive 0.11.0安装

使用mysql存储hive元数据
创建新的用户hive，密码也设为hive，并创建新的数据库名为hive,设定为latin1编码
赋予并刷新权限
grant all on hive.* to hive@'%'  identified by 'hive';
grant all on hive.* to hive@'localhost'  identified by 'hive';
flush privileges; 

验证hive用户
mysql -uhive -phive
show databases;

把hive安装包解压到/usr/local/hive-0.11.0
添加环境变量
vi  .bash_profile
导入下面的环境变量
export HIVE_HOME=/usr/local/hive-0.11.0
export PATH=$PATH:$HIVE_HOME/bin

使其有效
source .bash_profile

复制2份hive-default.xml.template，分别命名为hive-default.xml和hive-site.xml
修复hive-site.xml以下配置
<property> 
   <name>javax.jdo.option.ConnectionURL </name> 
   <value>jdbc:mysql://localhost:3306/hive </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>
    <description>Username to use against metastore database</description>
</property>
<property> 
   <name>javax.jdo.option.ConnectionPassword </name> 
   <value>hive </value> 
</property>

拷贝mysql的驱动mysql-connector-java-5.1.6-bin.jar 到hive 的lib下面

执行hive命令
hive

测试输入 show database;

如果没把mysql驱动拷贝到lib目录，或者mysql服务未启动，则会报错
FAILED: Error in metadata: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask
