hadoop集羣sqoop2安裝指南

環境說明

操作系統：Ubuntu 14.04

集羣節點：

• Master
• slave1
• slave2

解壓並安裝

hadoop@Master:~$ sudo tar xvfz sqoop-1.99.6-bin-hadoop200.tar.gz 
hadoop@Master:~$ sudo mv sqoop-1.99.6-bin-hadoop200 /usr/local/sqoop
hadoop@Master:~$ sudo chmod -R 775 /usr/local/sqoop
hadoop@Master:~$ sudo chown -R hadoop:hadoop /usr/local/sqoop

修改環境變量

hadoop@Master:~$ sudo nano /etc/profile

#sqoop
export SQOOP_HOME=/usr/local/sqoop
export PATH=$SQOOP_HOME/bin:$PATH
export CATALINA_BASE=$SQOOP_HOME/server
export LOGDIR=$SQOOP_HOME/logs

hadoop@Master:~$ source /etc/profile

修改sqoop的環境變量

hadoop@Master:/$ sudo nano /usr/local/sqoop/server/conf/sqoop.properties 

#修改指向我的hadoop安裝目錄  
org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/usr/local/hadoop/etc/hadoop  

hadoop@Master:/$ sudo nano /usr/local/sqoop/server/conf/catalina.properties 

common.loader=/usr/local/hadoop/share/hadoop/common/*.jar,/usr/local/hadoop/share/hadoop/common/lib/*.jar,/usr/local/hadoop/share/hadoop/hdfs/*.jar,/usr/local/hadoop/share/hadoop/hdfs/lib/*.jar,/usr/local/hadoop/share/hadoop/mapreduce/*.jar,/usr/local/hadoop/share/hadoop/mapreduce/lib/*.jar,/usr/local/hadoop/share/hadoop/tools/*.jar,/usr/local/hadoop/share/hadoop/tools/lib/*.jar,/usr/local/hadoop/share/hadoop/yarn/*.jar,/usr/local/hadoop/share/hadoop/yarn/lib/*.jar,/usr/local/hadoop/share/hadoop/httpfs/tomcat/lib/*.jar,

下載mysql驅動包，mysql-connector-java-5.1.27.jar

把jar包丟到到$SQOOP_HOME/server/lib下面

$ sudo cp mysql-connector-java-5.1.27.jar $SQOOP_HOME/server/lib

有時，啓動sqoop時可能會遇到找不到JAVA_HOME的情況，爲了保險起見我們直接在配置文件中寫入JAVA_HOME

#在/usr/local/sqoop/server/bin/setenv.sh中，添加
export JAVA_HOME=/usr/lib/jvm/

啓動sqoop

hadoop@Master:~/mysql-connector-java-5.0.8$ sqoop.sh server start
Sqoop home directory: /usr/local/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:   /usr/local/sqoop/server
Using CATALINA_HOME:   /usr/local/sqoop/server
Using CATALINA_TMPDIR: /usr/local/sqoop/server/temp
Using JRE_HOME:        /usr/lib/jvm//jre
Using CLASSPATH:       /usr/local/sqoop/server/bin/bootstrap.jar

驗證啓動成功

如果服務端已經啓動，則有Bootstrap這個進程：

hadoop@Master:~$ jps
...
13771 Bootstrap
