标签：INFO 22 04 Sqoop 29 SSL 17 组件 安装
1.实验一：Sqoop 组件安装与配置
1.1.实验目的
完成本实验，您应该能够：
-
下载和解压 Sqoop
-
配置Sqoop 环境
-
安装Sqoop
-
Sqoop 模板命令
1.2.实验要求
-
熟悉Sqoop 环境
-
熟悉Sqoop 模板命令
1.3.实验过程
1.3.1.实验任务一：下载和解压 Sqoop
安装Sqoop 组件需要与Hadoop 环境适配。使用 root 用户在Master 节点上进行部署， 将 /opt/software/sqoop-1.4.7.bin__hadoop-2.6.0.tar.gz 压 缩 包 解 压 到/usr/local/src 目录下。
[root@master ~]# tar xf /opt/software/sqoop-1.4.7.bin__hadoop-2.6.0.tar.gz -C /usr/local/src/
将解压后生成的 sqoop-1.4.7.bin hadoop-2.6.0 文件夹更名为 sqoop。
[root@master ~]# cd /usr/local/src/
[root@master src]# mv sqoop-1.4.7.bin__hadoop-2.6.0 sqoop
1.3.2.实验任务二：配置 Sqoop 环境
1.3.2.1.步骤一：创建 Sqoop 的配置文件 sqoop-env.sh。
复制 sqoop-env-template.sh 模板，并将模板重命名为 sqoop-env.sh。
[root@master src]# cd /usr/local/src/sqoop/conf/
[root@master conf]# cp sqoop-env-template.sh sqoop-env.sh
1.3.2.2.步骤二：修改 sqoop-env.sh 文件，添加 Hdoop、Hbase、Hive 等组件的安装路径。
注意，下面各组件的安装路径需要与实际环境中的安装路径保持一致。
vim sqoop-env.sh
export HADOOP_COMMON_HOME=/usr/local/src/hadoop
export HADOOP_MAPRED_HOME=/usr/local/src/hadoop
export HBASE_HOME=/usr/local/src/hbase
export HIVE_HOME=/usr/local/src/hive
1.3.2.3.步骤三：配置 Linux 系统环境变量，添加 Sqoop 组件的路径。
vim /etc/profile.d/sqoop.sh
export SQOOP_HOME=/usr/local/src/sqoop
export PATH=$SQOOP_HOME/bin:$PATH
export CLASSPATH=$CLASSPATH:$SQOOP_HOME/lib
[root@master conf]# source /etc/profile.d/sqoop.sh
[root@master conf]# echo $PATH
/usr/local/src/sqoop/bin:/usr/local/src/hbase/bin:/usr/local/src/zookeeper/bin:/usr/local/src/hbase/bin:/usr/local/src/jdk/bin:/usr/local/src/hadoop/bin:/usr/local/src/hadoop/sbin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/local/src/hive/bin:/root/bin
1.3.2.4.步骤四：连接数据库
为了使 Sqoop 能够连接 MySQL 数据库，需要将/opt/software/mysql-connector-jav a-5.1.46.jar 文件放入 sqoop 的 lib 目录中。该 jar 文件的版本需要与 MySQL 数据库的版本相对应，否则 Sqoop 导入数据时会报错。（mysql-connector-java-5.1.46.jar 对应的是 MySQL 5.7 版本）若该目录没有 jar 包,则使用第 6 章导入 home 目录的jar包
[root@master conf]# cp /opt/software/mysql-connector-java-5.1.46.jar /usr/local/src/sqoop/lib/
1.3.3.实验任务三：启动Sqoop
1.3.3.1.步骤一：执行 Sqoop 前需要先启动 Hadoop 集群。
在 master 节点切换到 hadoop 用户执行 start-all.sh 命令启动 Hadoop 集群。
[root@master conf]# su - hadoop
Last login: Fri Apr 22 16:21:25 CST 2022 on pts/0
[hadoop@master ~]$ start-all.sh
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
Starting namenodes on [master]
master: starting namenode, logging to /usr/local/src/hadoop/logs/hadoop-hadoop-namenode-master.out

10.10.10.130: starting nodemanager, logging to /usr/local/src/hadoop/logs/yarn-hadoop-nodemanager-slave2.out
10.10.10.129: starting nodemanager, logging to /usr/local/src/hadoop/logs/yarn-hadoop-nodemanager-slave1.out
1.3.3.2.步骤二：检查 Hadoop 集群的运行状态。
[hadoop@master ~]$ jps
1653 SecondaryNameNode
2086 Jps
1450 NameNode
1822 ResourceManager
[root@slave1 ~]# jps
1378 NodeManager
1268 DataNode
1519 Jps
[root@slave2 ~]# jps
1541 Jps
1290 DataNode
1405 NodeManager
1.3.3.3.步骤三：测试Sqoop是否能够正常连接MySQL 数据库。
Sqoop 连接 MySQL 数据库 P 大写 密码 Password123$
[hadoop@master ~]$ sqoop list-databases --connect jdbc:mysql://master:3306 --username root -P

You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

1.3.3.4.步骤四：连接 hive
为了使 Sqoop 能够连接 Hive，需要将 hive 组件/usr/local/src/hive/lib 目录下的
hive-common-2.0.0.jar 也放入 Sqoop 安装路径的 lib 目录中。
[hadoop@master ~]$ cp /usr/local/src/hive/lib/hive-common-2.0.0.jar /usr/local/src/sqoop/lib/
1.3.4.实验任务四：Sqoop 模板命令
1.3.4.1.步骤一：创建MySQL数据库和数据表。
