Hive01_安装部署

Hive的安装

上传安装包解压

shell 复制代码

tar zxvf apache-hive-3.1.2-bin.tar.gz
mv apache-hive-3.1.2-bin hive

解决Hive与Hadoop之间guava版本差异

shell 复制代码

cd /export/software/hive/
rm -rf lib/guava-19.0.jar

cp cp /export/software/hadoop/hadoop-3.3.0/share/hadoop/common/lib/guava-27.0-jre.jar /export/software/hive/lib

修改配置文件

hive-env.sh

shell 复制代码

cd /export/software/hive/conf
mv hive-env.sh.template hive-env.sh

vim hive-env.sh
export HADOOP_HOME=/export/software/hadoop/hadoop-3.3.0
export HIVE_CONF_DIR=/export/software/hive/conf
export HIVE_AUX_JARS_PATH=/export/software/hive/lib

hive-site.xml

shell 复制代码

vim hive-site.xml

xml 复制代码

上传mysql jdbc驱动到hive安装包lib下
```
mysql-connector-java-5.1.32.jar
```

初始化元数据

shell 复制代码

cd /export/software/hive

bin/schematool -initSchema -dbType mysql -verbos
#初始化成功会在mysql中创建74张表

在hdfs创建hive存储目录（如存在则不用操作）

shell 复制代码

hadoop fs -mkdir /tmp
hadoop fs -mkdir -p /user/hive/warehouse
hadoop fs -chmod g+w /tmp
hadoop fs -chmod g+w /user/hive/warehouse

1）启动 Hive

sh 复制代码

# 启动metastore服务
[root@node1 hive]$ bin/hive --service metastore &
[root@node1 hive]$ bin/hive

2）使用 Hive

sh 复制代码

hive> show databases;
hive> show tables;
hive> create table test (id int);
hive> insert into test values(1);
hive> select * from test;
