hive 结合mysql快速安装

系统使用centos7.1
官方下载hadoop,hive,jdk的安装包,解压在新建用户hive的目录下,安装mariadb-server(mysql-server)
[hive@localhost ~]$ ll

修改用户的环境
[hive@localhost ~]$ cat .bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs
export JAVA_HOME=/home/hive/jdk1.8.0_102
export HADOOP_HOME=/home/hive/hadoop-last
export HIVE_HOME=/home/hive/hive-last

PATH=$PATH:$HOME/.local/bin:$HOME/bin:$JAVA_HOME/bin:$HADOOP_HOME/bin:$HIVE_HOME/bin:$HIVE_HOME/conf

export PATH

启动mysql数据库,为hadoop/hive添加一个用户
[root@localhost ~]# systemctl start mariadb
[root@localhost ~]# mysql

进入$HIVE_HOME/conf,去掉以下三个文件的后辍.template
-rw-r--r-- 1 hive hive   2378 Sep 10 06:24 hive-env.sh
-rw-r--r-- 1 hive hive   2299 Jun  3 10:43 hive-exec-log4j2.properties
-rw-r--r-- 1 hive hive   2950 Sep 10 06:25 hive-log4j2.properties
重命令hive-default.xml.template为hive-site.xml
-rw-r--r-- 1 hive hive 225729 Sep 10 03:21 hive-site.xml
添加hive-env.sh两行
export HADOOP_HOME=/home/hive/hadoop-last
export HIVE_CONF_DIR=/home/hive/hive-last/conf
修改hive-site.xml
默认hive.metastore.warehouse.dir是/user/hive/warehouse
hive.exec.scratchdir是/tmp/hive
创建这个目录

如果是使用内置的derby存储metadata
[hive@localhost hive-last]$ schematool -dbType derby -initSchema
which: no hbase in (/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/hive/.local/bin:/home/hive/bin:/home/hive/jdk1.8.0_102/bin:/home/hive/hadoop-last/bin:/home/hive/hive-last/bin:/home/hive/hive-last/conf)

修改
chmod a+rw /tmp/hive/
下面修改为使用mysql

hive-site.xml
480:    javax.jdo.option.ConnectionPassword
481-    hive
498:    javax.jdo.option.ConnectionURL
499-    jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true
932:    javax.jdo.option.ConnectionDriverName
933-    com.mysql.jdbc.Driver
960:    javax.jdo.option.ConnectionUserName
961-    hive

下载mysql-connector
[hive@localhost mysql-connector-java-5.1.39]$ cp mysql-connector-java-5.1.39-bin.jar ~/hive-last/lib/ -v
‘mysql-connector-java-5.1.39-bin.jar’ -> ‘/home/hive/hive-last/lib/mysql-connector-java-5.1.39-bin.jar’


[hive@localhost hive-last]$ schematool -dbType mysql -initSchema

修改hive-site.xml的system变量,解决变量无法识别的问题,使用绝对路径
:%s#${system:java.io.tmpdir}#/tmp/javaiotmp#
:%s#${system:user.name}#hive#
