環境: Hadoop2.7.2(NameNode HA,ResourceManage HA)

1.下載
[root@sht-sgmhadoopnn-01 hadoop]# wget
[root@sht-sgmhadoopnn-01 hadoop]# tar -zxvf sqoop-1.99.6-bin-hadoop200.tar.gz
[root@sht-sgmhadoopnn-01 hadoop]# mv sqoop-1.99.6-bin-hadoop200 sqoop2

2.配置環境變數
[root@sht-sgmhadoopnn-01 ~]$ vim .bash_profile
新增如下內容：
export SQOOP_HOME=/hadoop/sqoop2
export CATALINA_HOME=$SQOOP_HOME/server
export LOGDIR=$SQOOP_HOME/logs
export PATH=$SQOOP_HOME/bin:$PATH
儲存退出即時生效：
[root@sht-sgmhadoopnn-01 ~]source .bash_profile

3.配置服務端
[root@sht-sgmhadoopnn-01 hadoop]# cd server/conf
[root@sht-sgmhadoopnn-01 conf]# pwd
/hadoop/sqoop2/server/conf
[root@sht-sgmhadoopnn-01 conf]#

[root@sht-sgmhadoopnn-01 conf]$ vi catalina.properties
common.loader=${catalina.base}/lib,${catalina.base}/lib/*.jar,${catalina.home}/lib,${catalina.home}/lib/*.jar,${catalina.home}/../lib/*.jar,/hadoop/hadoop/share/hadoop/common/*.jar,/hadoop/hadoop/share/hadoop/common/lib/*.jar,/hadoop/hadoop/share/hadoop/hdfs/*.jar,/hadoop/hadoop/share/hadoop/hdfs/lib/*.jar,/hadoop/hadoop/share/hadoop/mapreduce/*.jar,/hadoop/hadoop/share/hadoop/mapreduce/lib/*.jar,/hadoop/hadoop/share/hadoop/tools/lib/*.jar,/hadoop/hadoop/share/hadoop/tools/lib/*.jar,/hadoop/hadoop/share/hadoop/yarn/*.jar,/hadoop/hadoop/share/hadoop/yarn/lib/*.jar,/hadoop/hadoop/share/hadoop/httpfs/tomcat/lib/*.jar
###新增叢集環境的本機的jar的目錄

[root@sht-sgmhadoopnn-01 conf]$ vi sqoop.properties
org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/hadoop/hadoop/etc/hadoop

4.新增mysql driver
[root@sht-sgmhadoopnn-01 conf]$ cd /hadoop/sqoop2/server/lib
[root@sht-sgmhadoopnn-01 lib]# rz

#####建立job物件,這個別寫錯了，使用LINK ID,而不是 Connector Id
#####使用這兩個link Id來關聯job的From和To部分。說的通俗一點，就是我們需要從哪裡(From)讀取資料,把這些資料匯入(To)到哪裡
sqoop:000> create job -f 1 -t 2
