一.Hive安装地址
官网地址: http://hive.apache.org/ 文档查看地址: https://cwiki.apache.org/confluence/display/HIVE 下载地址: http://archive.apache.org/dist/hive/ 关于Hive版本适用于哪个Hadoop版本，可参考官方说明: http://hive.apache.org/downloads.html
二.部署Hive环境(使用默认derby的数据库)
1>.下载Hive支持hadoop 2.x的最新版本（可以使用wget工具进行下载，也可以在windows下载，而后直接上传到服务器端即可）
下载地址: http://archive.apache.org/dist/hive/hive-2.3.7/
2>.解压hive压缩包到指定目录并创建符号链接
[root@hadoop105.yinzhengjie.com ~]# tar -zxf apache-hive-2.3.7-bin.tar.gz -C /yinzhengjie/softwares/ [root@hadoop105.yinzhengjie.com ~]# cd /yinzhengjie/softwares/ [root@hadoop105.yinzhengjie.com /yinzhengjie/softwares]# [root@hadoop105.yinzhengjie.com /yinzhengjie/softwares]# ln -sv apache-hive-2.3.7-bin hive ‘hive’ -> ‘apache-hive-2.3.7-bin’ [root@hadoop105.yinzhengjie.com /yinzhengjie/softwares]#
3>.编辑hive-env.sh文件
[root@hadoop105.yinzhengjie.com ~]# cp /yinzhengjie/softwares/hive/conf/hive-env.sh.template /yinzhengjie/softwares/hive/conf/hive-env.sh [root@hadoop105.yinzhengjie.com ~]# [root@hadoop105.yinzhengjie.com ~]# grep "HIVE_CONF_DIR=" /yinzhengjie/softwares/hive/conf/hive-env.sh # export HIVE_CONF_DIR= [root@hadoop105.yinzhengjie.com ~]# [root@hadoop105.yinzhengjie.com ~]# sed -ri "s@# (export HIVE_CONF_DIR=)@1/yinzhengjie/softwares/hive/conf@" /yinzhengjie/softwares/hive/conf/hive-env.sh [root@hadoop105.yinzhengjie.com ~]# [root@hadoop105.yinzhengjie.com ~]# grep "HIVE_CONF_DIR=" /yinzhengjie/softwares/hive/conf/hive-env.sh export HIVE_CONF_DIR=/yinzhengjie/softwares/hive/conf [root@hadoop105.yinzhengjie.com ~]# [root@hadoop105.yinzhengjie.com ~]# [root@hadoop105.yinzhengjie.com ~]# grep "HADOOP_HOME=" /yinzhengjie/softwares/hive/conf/hive-env.sh # HADOOP_HOME=${bin}/../../hadoop [root@hadoop105.yinzhengjie.com ~]# [root@hadoop105.yinzhengjie.com ~]# sed -ri 's@# (HADOOP_HOME=)${bin}/../../hadoop@export 1/yinzhengjie/softwares/hadoop@' /yinzhengjie/softwares/hive/conf/hive-env.sh [root@hadoop105.yinzhengjie.com ~]# [root@hadoop105.yinzhengjie.com ~]# grep "HADOOP_HOME=" /yinzhengjie/softwares/hive/conf/hive-env.sh export HADOOP_HOME=/yinzhengjie/softwares/hadoop [root@hadoop105.yinzhengjie.com ~]#
4>.配置Hive的环境变量
[root@hadoop105.yinzhengjie.com ~]# vim /etc/profile.d/hive.sh [root@hadoop105.yinzhengjie.com ~]# [root@hadoop105.yinzhengjie.com ~]# cat /etc/profile.d/hive.sh #Add ${HIVE_HOME} by yinzhengjie HIVE_HOME=/yinzhengjie/softwares/hive PATH=$PATH:${HIVE_HOME}/bin [root@hadoop105.yinzhengjie.com ~]# [root@hadoop105.yinzhengjie.com ~]# source /etc/profile.d/hive.sh
5>.启动Hadoop集群
关于Hadoop集群的部署我这里就不罗嗦了，能看到这篇文章说明你对Hadoop的环境部署肯定是了解的，若不太了解的小伙伴可以自行参考我之前分享的笔记。
接下来我们要做的事情就是启动Hadoop集群。
[root@hadoop101.yinzhengjie.com ~]# manage-hdfs.sh start hadoop101.yinzhengjie.com | CHANGED | rc=0 >> starting namenode, logging to /yinzhengjie/softwares/hadoop-2.10.0-fully-mode/logs/hadoop-root-namenode-hadoop101.yinzhengjie.com.out hadoop105.yinzhengjie.com | CHANGED | rc=0 >> starting secondarynamenode, logging to /yinzhengjie/softwares/hadoop/logs/hadoop-root-secondarynamenode-hadoop105.yinzhengjie.com.out hadoop103.yinzhengjie.com | CHANGED | rc=0 >> starting datanode, logging to /yinzhengjie/softwares/hadoop/logs/hadoop-root-datanode-hadoop103.yinzhengjie.com.out hadoop102.yinzhengjie.com | CHANGED | rc=0 >> starting datanode, logging to /yinzhengjie/softwares/hadoop/logs/hadoop-root-datanode-hadoop102.yinzhengjie.com.out hadoop104.yinzhengjie.com | CHANGED | rc=0 >> starting datanode, logging to /yinzhengjie/softwares/hadoop/logs/hadoop-root-datanode-hadoop104.yinzhengjie.com.out Starting HDFS: [ OK ] [root@hadoop101.yinzhengjie.com ~]#

6>.安装数据库并授权
如下图所示，执行以下三条命令就可以完成授权啦:(一定要进行权限测试，还有就是要注意Hive支持的MySQL最低版本问题哟~) CREATE DATABASE hive_metastore CHARACTER SET utf8 COLLATE utf8_bin; CREATE USER hive@hadoop105.yinzhengjie.com IDENTIFIED BY 'yinzhengjie'; GRANT ALL PRIVILEGES ON hive_metastore.* TO hive@hadoop105.yinzhengjie.com; 博主推荐阅读:(下面的链接是关于部署MySQL的方法以及Hive支持的MySQL版本) https://www.cnblogs.com/yinzhengjie/p/11733897.html https://cwiki.apache.org/confluence/display/Hive/AdminManual+Metastore+Administration
7>.拷贝MySQL的驱动包到hive的依赖库目录
[root@hadoop105.yinzhengjie.com ~]# ll /yinzhengjie/softwares/hive/lib/ | wc -l 256 [root@hadoop105.yinzhengjie.com ~]# [root@hadoop105.yinzhengjie.com ~]# ll # 驱动包直接在Oracle官网就可以下载哟，如果你安装的MySQL版本较高，选择驱动时也应该选择对应的版本！(当然这也依赖于Hive是否支持更高版本的数据库哟~) total 852 -rw-r--r-- 1 root root 872303 Mar 1 2020 mysql-connector-java-5.1.27-bin.jar [root@hadoop105.yinzhengjie.com ~]# [root@hadoop105.yinzhengjie.com ~]# mv mysql-connector-java-5.1.27-bin.jar /yinzhengjie/softwares/hive/lib/ [root@hadoop105.yinzhengjie.com ~]# [root@hadoop105.yinzhengjie.com ~]# ll /yinzhengjie/softwares/hive/lib/ | wc -l 257 [root@hadoop105.yinzhengjie.com ~]# [root@hadoop105.yinzhengjie.com ~]#
8>.配置Hive的MetaStore到MySQL
[root@hadoop105.yinzhengjie.com ~]# vim /yinzhengjie/softwares/hive/conf/hive-site.xml [root@hadoop105.yinzhengjie.com ~]# [root@hadoop105.yinzhengjie.com ~]# cat /yinzhengjie/softwares/hive/conf/hive-site.xml <?xml version="1.0"?> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?> <configuration> <!-- 配置数据库链接相关的参数 --> <property> <name>javax.jdo.option.ConnectionURL</name> <value>jdbc:mysql://hadoop101.yinzhengjie.com:3306/hive_metastore?createDatabaseIfNotExist=true</value> <description> JDBC connect string for a JDBC metastore.

9>.初始化元数据库
[root@hadoop105.yinzhengjie.com ~]# schematool -initSchema -dbType mysql SLF4J: Class path contains multiple SLF4J bindings.

10>.查看数据仓库的默认数据库
11>.创建一张表，观察元数据库及HDFS集群中的变化
Hive终端执行的操作如下所示:
hive> CREATE TABLE teachers (id int, name string, address string);
MySQL终端执行的操作如下所示: MySQL [hive_metastore]> select * from DBS; +-------+-----------------------+-----------------------------------------------------------+---------+------------+------------+ | DB_ID | DESC | DB_LOCATION_URI | NAME | OWNER_NAME | OWNER_TYPE | +-------+-----------------------+-----------------------------------------------------------+---------+------------+------------+ | 1 | Default Hive database | hdfs://hadoop101.yinzhengjie.com:9000/user/hive/warehouse | default | public | ROLE | +-------+-----------------------+-----------------------------------------------------------+---------+------------+------------+ 1 row in set (0.00 sec) MySQL [hive_metastore]> select * from TBLS; Empty set (0.00 sec) MySQL [hive_metastore]> MySQL [hive_metastore]> select * from TBLS; +--------+-------------+-------+------------------+-------+-----------+-------+----------+---------------+--------------------+--------------------+--------------------+ | TBL_ID | CREATE_TIME | DB_ID | LAST_ACCESS_TIME | OWNER | RETENTION | SD_ID | TBL_NAME | TBL_TYPE | VIEW_EXPANDED_TEXT | VIEW_ORIGINAL_TEXT | IS_REWRITE_ENABLED | +--------+-------------+-------+------------------+-------+-----------+-------+----------+---------------+--------------------+--------------------+--------------------+ | 1 | 1605529291 | 1 | 0 | root | 0 | 1 | teachers | MANAGED_TABLE | NULL | NULL | | +--------+-------------+-------+------------------+-------+-----------+-------+----------+---------------+--------------------+--------------------+--------------------+ 1 row in set (0.00 sec) MySQL [hive_metastore]>
