hive 安装配置

hive 安装配置

检查 mysqld 进程是否已经开启：

$pgrep mysqld

如果进程开启，这个命令将会返回该进程的 id

进入MySQL

$mysql -u root -p

安装hive

解压

tar–zxvf apache-hive-1.1.0-bin.tar.gz

profile配置环境变量

执行命令

$sudo gedit /etc/profile

注意CLASSPATH，PATH在原有上增加hive包路径

#set hive environment

HIVE_HOME=/home/hadoop/hive-1.1.0

PATH=$HIVE_HOME/bin:$PATH

CLASSPATH=$CLASSPATH:$HIVE_HOME/lib

export HIVE_HOME

export PATH

export CLASSPATH

 

使配置生效：

$source /etc/profile

配置hive-env.sh

gedit /home/yuqiao/hive-0.9.0/conf hive-env.sh

 

# Set HADOOP_HOME to point to a specific hadoop install directory

HADOOP_HOME=/home/yuqiao/hadoop-2.7.1

# Hive Configuration Directory can be controlled by:

export HIVE_CONF_DIR=/home/yuqiao/hive-0.9.0/conf

配置hive-site.xml

创建配置文件

$cp hive-default.xml.template  hive-site.xml

hive.metastore.warehouse.dir，hive.exec.scratchdir【 hdfs目录】会自动创建

在hive下创建local文件夹

配置log4j

 

在同上目录下

创建配置文件：

cp hive-exec-log4j.properties.template  hive-exec-log4j.properties

cp hive-log4j.properties.template  hive-log4j.properties

修改上面两个文件中的配置

hive.log.dir=/home/hadoop/ hive-1.1.0/logs

log4j.appender.EventCounter=org.apache.hadoop.log.metrics.EventCounter

注意如果没有logs目录就建立一个 执行命令

$mkdir /home/hadoop/hive-1.1.0/logs

添加Mysql驱动包

   把驱动包mysql-connector-java-5.1.24-bin.jar

放到 $HIVE_HOME/lib 目录下

 

 

修改profile

 

启动hive

 

执行命令

$start-dfs.sh

$hive

有些如insert into需要执行mr,需要打开start-yarn.sh
