sqoop是一個把關系型數據庫數據抽向hadoop的工具。同時，也支持將hive、pig等查詢的結果導入關系型數據庫中存儲。
由於，筆者部署的hadoop版本是2.2.0，所以sqoop的版本是：sqoop-1.99.3-bin-hadoop200
1、下載sqoop wget http://mirrors.cnnic.cn/apache/sqoop/1.99.3/sqoop-1.99.3-bin-hadoop200.tar.gz
2、解壓sqoop安裝文件 tar -zxvf sqoop-1.99.3-bin-hadoop200.tar.gz
3、配置sqoop環境變量
export SQOOP_HOME=/home/likehua/sqoop/sqoop
export PATH = $SQOOP_HOME/bin:$PATH
修改sqoop——server關於hadoop共享jar的引用
vi server/conf/catalina.properties
找到common.loader行，把/usr/lib/hadoop/lib/*.jar改成你的hadoop jar 包目錄
例如:/home/hadoop/hadoop/share/hadoop/yarn/lib/*.jar,
/home/hadoop/hadoop/share/hadoop/yarn/*.jar,
/home/hadoop/hadoop/share/hadoop/hdfs/*.jar,
/home/hadoop/hadoop/share/hadoop/hdfs/lib/*.jar,
/home/hadoop/hadoop/share/hadoop/mapreduce/*.jar,
/home/hadoop/hadoop/share/hadoop/mapreduce/lib/*.jar,
/home/hadoop/hadoop/share/hadoop/common/lib/*.jar,
/home/hadoop/hadoop/share/hadoop/common/*.jar
vi server/conf/sqoop.properties
找到：mapreduce.configuration.directory行，修改值為你的hadoop配置文件目錄
如：/home/likehua/hadoop/hadoop/etc/hadoop
並且替換@LOGDIR@ 和@BASEDIR@ ：
0,$ s/@LOGDIR@/logs/g
0,$ s/@BASEDIR@/base/g
然后找到你的數據庫jdbc驅動復制到sqoop/lib目錄下，如果不存在則創建.
vi /etc/profile
增加以下內容：
export SQOOP_HOME=/home/hadoop/sqoop
export PATH=$PATH:$SQOOP_HOME/bin
export CATALINA_BASE=$SQOOP_HOME/server
export LOGDIR=$SQOOP_HOME/logs/
啟動 [root@db12c sqoop]# ./bin/sqoop.sh server start
Sqoop home directory: /home/likehua/sqoop/sqoop
Setting SQOOP_HTTP_PORT: 12000
Setting SQOOP_ADMIN_PORT: 12001
Using CATALINA_OPTS:
Adding to CATALINA_OPTS: -Dsqoop.http.port=12000 -Dsqoop.admin.port=12001
Using CATALINA_BASE: /home/likehua/sqoop/sqoop/server
Using CATALINA_HOME: /home/likehua/sqoop/sqoop/server
Using CATALINA_TMPDIR: /home/likehua/sqoop/sqoop/server/temp
Using JRE_HOME: /usr/local/jdk1.7.0
Using CLASSPATH: /home/likehua/sqoop/sqoop/server/bin/bootstrap.jar
(sqoop服務端是一個跑在tomcat上的服務程序)
關閉 sqoop server :./bin/sqoop.sh server stop
使用sqoop客戶端：
[root@db12c sqoop]# bin/sqoop.sh client
Sqoop home directory: /home/likehua/sqoop/sqoop
Sqoop Shell: Type 'help' or '\h' for help.
