Mac上Hive安装配置

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-3.0.0-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-3.0.0-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: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/usr/local/hive/lib/log4j-slf4j-impl-2.10.0.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/opt/hadoop-2.7.6/share/hadoop/common/lib/slf4j-log4j12-1.7.10.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://172.16.114.132:3306/hive
Metastore Connection Driver :    com.mysql.jdbc.Driver
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！
