Mac上Hive安装配置
1、安装
下载hive，地址:http://mirror.bit.edu.cn/apache/hive/
之前我配置了集群，tjt01、tjt02、tjt03，这里hive安装在tjt01机器上。
我下载的是“apache-hive-3.0.0-bin.tar.gz”，将hive 3.0版本上传到/opt目录，并解压到/usr/local下:
[root@tjt01 ~]# cd /opt
[root@tjt01 opt]# tar -zxvf apache-hive-3.0.-bin.tar.gz -C /usr/local/
将目录重命名为hive目录:
[root@tjt01 opt]# cd /usr/local/
[root@tjt01 local]# mv apache-hive-3.0.-bin hive
[root@tjt01 local]#
修改环境变量/etc/profile:
[root@tjt01 local]# vi /etc/profile
在profile文件中添加如下内容：
export HIVE_HOME=/usr/local/hive
export PATH=$PATH:$HIVE_HOME/bin
生效profile：
[root@tjt01 local]# vi /etc/profile
[root@tjt01 local]# source /etc/profile
执行 hive --version查看hive版本
[root@tjt01 local]# hive --version

[root@tjt01 local]#
2、安装Mysql
我之前安装过了，Mysql安装参考：https://www.cnblogs.com/taojietaoge/p/10692557.html
启动Mysql服务：
[root@tjt03 ~]# sudo service mysqld start
启动过程报错了下，简单解决如下：
[root@tjt03 ~]# /etc/init.d/mysqld start
Starting mysqld (via systemctl): Job for mysqld.service failed because the control process exited with error code. See "systemctl status mysqld.service" and "journalctl -xe" for details.
[FAILED]
[root@tjt03 ~]# mkdir /var/run/mysqld/
[root@tjt03 ~]# chown mysql.mysql /var/run/mysqld/
[root@tjt03 ~]# sudo service mysqld start
Starting mysqld (via systemctl): [ OK ]
[root@tjt03 ~]#
设置Mysql开机启动：
[root@tjt03 ~]# systemctl enable mysqld
mysqld.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig mysqld on
[root@tjt03 ~]# systemctl daemon-reload
[root@tjt03 ~]#
3、配置
3.1 修改hive-site.xml
[root@tjt01 conf]# cd ~
[root@tjt01 ~]# cd /usr/local/hive/conf/
[root@tjt01 conf]# cp hive-default.xml.template hive-site.xml
[root@tjt01 conf]# vim hive-site.xml
xml内容如下：
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://172.16.114.132:3306/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>root</value>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>TANjintao@520</value>
</property>
<property>
<name>hive.metastore.schema.verification</name>
<value>false</value>
</property>
</configuration>
3.2 复制Mysql的程序程序到hive/lib下
mysql-connector-java.jar
3.3 创建Mysql下的hive数据库
mysql> create database hive;
Query OK, 1 row affected (0.01 sec)
mysql>
3.4 在Mysql中hive的schema创建
[root@tjt01 bin]# schematool -dbType mysql -initSchema

SLF4J: Actual binding is of type [org.apache.logging.slf4j.Log4jLoggerFactory]
Metastore connection URL: jdbc:mysql://172.16.114.132:3306/hive

Metastore connection User: root
Starting metastore schema initialization to 3.0.0
Initialization script hive-schema-3.0.0.mysql.sql Initialization script completed
schemaTool completed
[root@tjt01 bin]#
4、测试
进入hive之前，开启hadoop，键入hive进入hive：
[root@tjt01 bin]# start-dfs.sh
Starting namenodes on [tjt01]
tjt01: starting namenode, logging to /opt/hadoop-2.7.6/logs/hadoop-root-namenode-tjt01.out
tjt03: starting datanode, logging to /opt/hadoop-2.7.6/logs/hadoop-root-datanode-tjt03.out
tjt02: starting datanode, logging to /opt/hadoop-2.7.6/logs/hadoop-root-datanode-tjt02.out
tjt01: starting datanode, logging to /opt/hadoop-2.7.6/logs/hadoop-root-datanode-tjt01.out
Starting secondary namenodes [tjt02]
tjt02: starting secondarynamenode, logging to /opt/hadoop-2.7.6/logs/hadoop-root-secondarynamenode-tjt02.out
[root@tjt01 bin]#hive
创建hive数据库：
hive> create database hive_1;
OK
Time taken: 0.709 seconds
hive> show databases;
OK
default
hive_1
Time taken: 0.238 seconds, Fetched: 2 row(s)
hive>
观察Mysql下hive数据库的变化：
mysql> select * from DBS;
在hive_1下创建一个hive_01:
hive> use hive_1;
OK
Time taken: 0.066 seconds
hive> create table hive_01 (id int, name string);
OK
Time taken: 1.235 seconds
hive>
再次观察Mysql下hive数据库的变化：
mysql> select * from TBLS;
到此为止，Mac安装Hive完美收官！
