Sqoop2的安装
1. 解压并安装
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
2. 修改环境变量
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
3. 修改sqoop的环境变量
hadoop@Master:/$ sudo nano /usr/local/sqoop/conf/sqoop.properties
#修改指向我的hadoop安装目录
org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/usr/local/hadoop/etc/hadoop
#catalina.properties 此文件不存在,需要自已建立
hadoop@Master:/$ sudo nano /usr/local/sqoop/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,
下载mysql驱动包，mysql-connector-java-5.1.27.jar
把jar包丢到到$SQOOP_HOME/server/lib下面
sudo cp mysql-connector-java-5.1.27.jar $SQOOP_HOME/server/lib
有时，启动sqoop时可能会遇到找不到JAVA_HOME的情况，为了保险起见我们直接在配置文件中写入JAVA_HOME
在/usr/local/sqoop/bin/sqoop.sh中，添加
export JAVA_HOME=/usr/lib/jvm/
HADOOP_COMMON_HOME=/usr/local/hadoop/share/hadoop/common
HADOOP_HDFS_HOME=/usr/local/hadoop/share/hadoop/hdfs
HADOOP_MAPRED_HOME=/usr/local/hadoop/share/hadoop/mapreduce
HADOOP_YARN_HOME=/usr/local/hadoop/share/hadoop/yarn
4. 启动sqoop
hadoop@Master:~/mysql-connector-java-5.0.8$ 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
5. 验证启动成功
./sqoop.sh server start 启动
./sqoop.sh server stop 停止
./sqoop.sh client 进入客户端
set server --host hadoopMaster --port 12000 --webapp sqoop 设置服务器，注意hadoopMaster为hdfs主机名
show connector --all 查看连接类型
create link --cid 1 创建连接，cid为连接类型id
show link 查看连接
update link -l 1 修改id为1的连接
delete link -l 1 删除id为1的连接
create job -f 1 -t 2 创建从连接1到连接2的job
show job 查看job
update job -jid 1 修改job
delete job -jid 1 删除job
status job -jid 1 看看job状态
stop job -jid 1 停止job
6.Hadoop的配置修改
需要在Hadoop的yarn-site.xml 这个配置文件中增加以下属性
<property>
<name>yarn.log-aggregation-enable</name>
<value>true</value>
</property>
