【Sqoop1】Sqoop1安装

本篇主要演示在Linux上基于Hadoop安装Sqoop1。

一安装环境

操作系统：Oracle Linux Server release 6.5；
Java版本：java-1.7.0-openjdk-1.7.0.45；
Hadoop版本：hadoop-2.7.6；
Sqoop2版本：1.4.7；

二安装前准备

1 安装Hadoop

具体安装过程参考： Hadoop 2.7.6安装_伪分布式集群

2 下载Sqoop1以及MySQL-jdbc

Sqoop1下载地址： http://mirror.bit.edu.cn/apache/sqoop/1.4.7/

MySQL Connector 下载地址： https://dev.mysql.com/downloads/connector/j/

三安装配置Sqoop1

1 解压缩安装包

[root@strong ~]# tar zxvf sqoop-1.4.7.bin__hadoop-2.6.0.tar.gz
[root@strong ~]# mv sqoop-1.4.7.bin__hadoop-2.6.0 sqoop-1.4.7
[root@strong ~]# chown -R hadoop:hadoop sqoop-1.4.7

2 修改配置文件

[root@strong ~]# cp sqoop-env-template.sh sqoop-env.sh
[hadoop@strong conf]$ vim sqoop-env.sh
#Set path to where bin/hadoop is available
export HADOOP_COMMON_HOME=/usr/local/hadoop

#Set path to where hadoop-*-core.jar is available
export HADOOP_MAPRED_HOME=/usr/local/hadoop

#set the path to where bin/hbase is available
export HBASE_HOME=/usr/local/hbase

#Set the path to where bin/hive is available
export HIVE_HOME=/usr/local/apache-hive-2.3.3-bin

export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.45.x86_64

3 拷贝Mysql驱动至Lib目录

[hadoop@strong ~]$ cp /usr/local/apache-hive-2.3.3-bin/lib/mysql-connector-java-5.1.46.jar /usr/local/sqoop-1.4.7/lib/

4 查看版本信息

[hadoop@strong ~]$ sqoop version

Tue Jun 26 11:50:54 CST 2018 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.
