2.解压
》tar -zxvf apache-hive-2.3.3-bin.tar.gz
3.修改配置文件
》cd conf/
》cp hive-env.sh.template hive-env.sh
》vim hive-env.sh
（添加如下两行）
export HADOOP_HOME=/opt/soft/hadoop-2.7.5
export HIVE_CONF_DIR=/opt/soft/apache-hive-2.3.3-bin/conf
》cp hive-default.xml.template hive-site.xml
》vim hive-site.xml
（修改一下内容）

4. 初始化
》pwd
/opt/soft/apache-hive-2.3.3-bin/bin
》 ./bin/schematool -dbType mysql -initSchema
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in
[jar:file:/opt/soft/apache-hive-2.3.3-bin/lib/log4j-slf4j-impl-2.6.2.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in

SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.apache.logging.slf4j.Log4jLoggerFactory]

二： 安装过程出现的问题
1.Exception in thread "main" java.lang.IllegalArgumentException: java.net.URISyntaxException: Relative path in absolute URI: ${system:java.io.tmpdir%7D/$%7Bsystem:user.name%7D
（参考：https://blog.csdn.net/cds86333774/article/details/51135954）
2.初始化过程出现问题
org.apache.hadoop.hive.metastore.HiveMetaException: Failed to get schema version.
Underlying cause: java.sql.SQLException : Access denied for user 'oss2'@'mysql-master' (using password: YES)
SQL Error code: 1045
Use --verbose for detailed stacktrace.
*** schemaTool failed ***
原因：没有授权
需要在mysql数据库中操作：（用户名：oss2. 密码： Unicom_911，主机名：mysql-master）
GRANT ALL PRIVILEGES ON *.* TO 'oss2'@'mysql-master' IDENTIFIED BY 'Unicom_911' WITH GRANT OPTION;
FLUSH PRIVILEGES
重新初始化，问题解决
