配置Hive环境变量

将Hive的bin目录添加到系统环境变量中。

[root@master local]# vi /etc/profile
# Hive
export HIVE_HOME=/usr/local/apache-hive-2.3.9-bin
export PATH=$PATH:$HIVE_HOME/bin

[root@master local]# source /etc/profile

配置Hive配置文件

[root@master local]# cd apache-hive-2.3.9-bin/conf

[root@master conf]# vi hive-env.sh.template
HADOOP_HOME=$HADOOP_HOME
export HIVE_CONF_DIR=$HIVE_HOME/conf

修改Hive的配置文件hive-site.xml，设置Hive的元数据存储方式、Hadoop的配置文件路径等。

启动Hive

在命令行中输入hive命令，启动Hive。

[root@master conf]# hdfs namenode -format
[root@master conf]# start-dfs.sh
[root@master conf]# start-yarn.sh
[root@master conf]# hive
