一、sqoop简介

Sqoop是一款开源的工具，主要用于在Hadoop(Hive)与传统的数据库(mysql、postgresql…)间进行数据的传递，可以将一个关系型数据库（例如 ： MySQL ,Oracle ,Postgres等）中的数据导进到Hadoop的HDFS中，也可以将HDFS的数据导进到关系型数据库中。

说明：本测试hadoop是单机伪分布式环境，如果读者想要学习如何搭建伪分布式hadoop环境请看本人这篇文章([Hadoop+Hive+HBase+Kylin 伪分布式安装指南(https://www.geek-share.com/detail/2763619456.html))，本文章只介绍如何安装部署sqoop，后续通过sqoop将Oracle数据导入到hadoop环境实验在另外一篇文章，待测试完将会把连接放到此文章。

二、环境配置

三、安装Sqoop

1. 下载，解压到指定目录

下载连接：

点此下载
创建安装目录，通过xshell上传安装包

[root@hadoop hadoop]# pwd
/hadoop
[root@hadoop hadoop]# mkdir sqoop
[root@hadoop hadoop]# cd sqoop/
[root@hadoop sqoop]# ls
sqoop-1.4.7.bin__hadoop-2.6.0.tar.gz
[root@hadoop sqoop]# tar -zxvf sqoop-1.4.7.bin__hadoop-2.6.0.tar.gz
[root@hadoop sqoop]# ls
sqoop-1.4.7.bin__hadoop-2.6.0  sqoop-1.4.7.bin__hadoop-2.6.0.tar.gz
[root@hadoop sqoop]# rm -rf *gz
[root@hadoop sqoop]# mv sqoop-1.4.7.bin__hadoop-2.6.0/* .

2、修改配置文件sqoop-env.sh

在sqoop/conf目录下有一个文件sqoop-env-template.sh，把它复制为sqoop-env.sh并修改

[root@hadoop sqoop]# cd conf/
[root@hadoop conf]# cp sqoop-env-template.sh sqoop-env.sh
#Set path to where bin/hadoop is available
[root@hadoop conf]# vim sqoop-env.sh
根据自己情况修改，另外，你还装了Zookeeper的话则最后一句也要配置。
export HADOOP_COMMON_HOME=/hadoop/

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

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

#Set the path to where bin/hive is available
export HIVE_HOME=/hadoop/hive

#Set the path for where zookeper config dir is
#export ZOOCFGDIR=

3. 配置环境变量

我测试用户为root用户，直接修改/etc/profile加入下面内容：

export SQOOP_HOME=/hadoop/sqoop
export PATH=$PATH:${SQOOP_HOME}/bin
export CLASSPATH=$CLASSPATH:${SQOOP_HOME}/lib

然后使环境变量生效

[root@hadoop conf]# source /etc/profile

4. 复制相关依赖包到$SQOOP_HOME/lib

因为我是将Oracle数据导入到hive，所以复制环境数据库所在虚拟机(195.168.1.6)的Oracle的OJDBC包到/hadoop/sqoop/lib下

[oracle@source ~]$ cd $ORACLE_HOME/jdbc/lib
[oracle@source lib]$ pwd
/u01/app/oracle/product/11.2.0/db_1/jdbc/lib
[oracle@source lib]$ ls
ojdbc5dms_g.jar  ojdbc5_g.jar  ojdbc6dms_g.jar  ojdbc6_g.jar  simplefan.jar
ojdbc5dms.jar    ojdbc5.jar    ojdbc6dms.jar    ojdbc6.jar
上面是数据库所在虚拟机Oraclejar包位置及信息。将ojdbc包传到hadoop虚拟机
[oracle@source lib]$ scp ojdbc6.jar root@192.168.1.66:/hadoop/sqoop/lib
root@192.168.1.66's password:
ojdbc6.jar                                                           100% 2675KB   2.6MB/s   00:00

5、修改$SQOOP_HOME/bin/configure-sqoop

注释掉HCatalog，Accumulo检查(除非你准备使用HCatalog，Accumulo等HADOOP上的组件)

##Moved to be a runtime check in sqoop.
#if[ ! -d "${HCAT_HOME}" ]; then
#  echo "Warning: $HCAT_HOME does notexist! HCatalog jobs will fail."
#  echo 'Please set $HCAT_HOME to the root ofyour HCatalog installation.'
#fi

#if[ ! -d "${ACCUMULO_HOME}" ]; then
#  echo "Warning: $ACCUMULO_HOME does notexist! Accumulo imports will fail."
#  echo 'Please set $ACCUMULO_HOME to the rootof your Accumulo installation.'
#fi

#Add HCatalog to dependency list
#if[ -e "${HCAT_HOME}/bin/hcat" ]; then
# TMP_SQOOP_CLASSPATH=${SQOOP_CLASSPATH}:`${HCAT_HOME}/bin/hcat-classpath`
#  if [ -z "${HIVE_CONF_DIR}" ]; then
#   TMP_SQOOP_CLASSPATH=${TMP_SQOOP_CLASSPATH}:${HIVE_CONF_DIR}
#  fi
#  SQOOP_CLASSPATH=${TMP_SQOOP_CLASSPATH}
#fi

#Add Accumulo to dependency list
#if[ -e "$ACCUMULO_HOME/bin/accumulo" ]; then
#  for jn in `$ACCUMULO_HOME/bin/accumuloclasspath | grep file:.*accumulo.*jar |cut -d':' -f2`; do
#    SQOOP_CLASSPATH=$SQOOP_CLASSPATH:$jn
#  done
#  for jn in `$ACCUMULO_HOME/bin/accumuloclasspath | grep file:.*zookeeper.*jar |cut -d':' -f2`; do
#    SQOOP_CLASSPATH=$SQOOP_CLASSPATH:$jn
#  done
#fi

6、 测试与Oracle的连接

[root@hadoop sqoop]# pwd
/hadoop/sqoop
[root@hadoop sqoop]# sqoop list-databases --connect jdbc:oracle:thin:@192.168.1.6:1521:orcl --username scott --password tiger
Warning: /hadoop/sqoop/../zookeeper does not exist! Accumulo imports will fail.
Please set $ZOOKEEPER_HOME to the root of your Zookeeper installation.
