Hadoop2.7实战v1.0之Hive-2.0.0+MySQL远程模式安装  http://m.blog.itpub.net/30089851/viewspace-2082805/

安装环境

Ubuntu 12.04 server

java 1.7.0_95

hadoop 2.6.4

步骤：

1、安装mysql

直接使用命令安装:

更新源

sudo apt-get update

安装

sudo apt-get install mysql-server mysql-client

2、Mysql创建新用户以及数据库并授权

mysql> create database hive_remote_meta;
Query OK, 1 row affected (0.04 sec)

mysql> create user ‘hive‘ identified by ‘hive‘;
Query OK, 0 rows affected (0.05 sec)

mysql> grant all privileges on hive_remote_meta.* to ‘hive‘@‘%‘;
Query OK, 0 rows affected (0.03 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)

查看Mysql监听地址

nestart -an | grep 3306tcp        0      0 127.0.0.1:3306          0.0.0.0:*               LISTEN

结果如上即修改Mysql监听IP地址

sudo vim /etc/mysql/my.cnf

# localhost which is more compatible and is not less secure.
bind-address          = 127.0.0.1 #注释掉
#
# * Fine Tuning

3、安装hive

官网下载hive2.0安装包

解压到指定文件夹

sudo tar -zxvf apache-hive-2.0.0-bin.tar.gz -C /you_hive_path

配置环境变量

sudo vim ~/.bashrcexport HIVE_HOME=/you_hive_path/apache-hive-2.0.0-binexport PATH=$PATH:$HIVE_HOME/bin

4、配置hive-size.xml文件,位于 HIVE_HOME下的conf中，新建。

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

<configuration>

      <property>　　　　　#设置为本地仓库
        <name>hive.metastore.local</name>
        <value>true</value>
      </property>

      <property>　　　　　#设置仓库地址， value更换为你创建的mysql数据库
        <name>javax.jdo.option.ConnectionURL</name>
        <value>jdbc:mysql://Master:3306/hive_remote_meta?characterEncoding=UTF-8</value>
        <description>JDBC connect string for a JDBC metastore</description>
     </property>
     <property>　　　　　#设置使用 JDBC
        <name>javax.jdo.option.ConnectionDriverName</name>
        <value>com.mysql.jdbc.Driver</value>
        <description>Driver class name for a JDBC metastore</description>
     </property>

     <property>　　　　　#数据库用户名
        <name>javax.jdo.option.ConnectionUserName</name>
        <value>hive</value>
        <description>username to use against metastore database</description>
     </property>
     <property>         #数据库密码
        <name>javax.jdo.option.ConnectionPassword</name>
        <value>hive</value>
        <description>password to use against metastore database</description>
     </property>

</configuration>

5、初始化hive仓库

schematool -initSchema -dbType mysql

SLF4J: Class path contains multiple SLF4J bindings.

SLF4J: Found binding in [jar:file:/usr/local/hadoop/hive/apache-hive-2.0.0-bin/lib/hive-jdbc-2.0.0-standalone.jar!/org/slf4j/impl/StaticLoggerBinder.class]

SLF4J: Found binding in [jar:file:/usr/local/hadoop/hive/apache-hive-2.0.0-bin/lib/log4j-slf4j-impl-2.4.1.jar!/org/slf4j/impl/StaticLoggerBinder.class]SLF4J: Found binding in [jar:file:/usr/local/hadoop/share/hadoop/common/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.SLF4J: Actual binding is of type [org.apache.logging.slf4j.Log4jLoggerFactory]Metastore connection URL:	jdbc:mysql://Master:3306/hive_remote_meta?createDatabaseIfNotExist=trueMetastore Connection Driver :	com.mysql.jdbc.DriverMetastore connection User:	hiveStarting metastore schema initialization to 2.0.0Initialization script hive-schema-2.0.0.mysql.sqlInitialization script completedschemaTool completed

6、启动

hive

hive>

若出现

Name node is in safe mode.

则关闭hdfs安全模式

hadoop dfsadmin -safemode leave

完。
