不多说,直接上干货!
首先,说下博主我,为什么,好端端的Sqoop1用的好好的,然后又安装和学习Sqoop2?
因为,在Cloudera Hue里的Sqoop,是需要Sqoop2。
HUE配置文件hue.ini 的sqoop模块详解(图文详解)(分HA集群)
Sqoop2安装简介
sqoop2的安装分为server端和client端。
server端:负责与hadoop集群通信进行数据的迁移,client端负责与用户和server交互。
client端:不用安装, 只需要将其安装包解压到集群中任何的机器上去,然后对其进行解压即可, 无需其他额外的配置。
Sqoop分client和server,server安装在Hadoop或Spark集群中的某个节点上,这个节点充当要连接sqoop的入口节点,
client端不需要安装hadoop。
本博文是个入门,即只在bigdatamaster上安装server端。当然你也可以假设认为server和client都在bigdatamaster上哈。
对于Sqoop和hive这样的组件,我一般都是安装在master节点,即在本博客里是bigdatamaster。

配置环境变量
[hadoop@bigdatamaster sqoop]$ su root
Password:
[root@bigdatamaster sqoop]# vim /etc/profile
#sqoop1
#export SQOOP_HOME=/home/hadoop/app/sqoop
#export PATH=$PATH:$SQOOP_HOME/bin #sqoop2
export SQOOP_HOME=/home/hadoop/app/sqoop
export PATH=$PATH:$SQOOP_HOME/bin
export CATALINA_BASE=/home/hadoop/app/sqoop/server
export LOGDIR=$SQOOP_HOME/logs/
对于Sqoop2的server端安装配置(说明)
- 解压软件包到一个目录下。(我一般是放在/home/hadoop/app下)
- 修改环境变
export SQOOP_HOME=/home/hadoop/app/sqoop (因为我是用的软链接)
export PATH=$PATH:$SQOOP_HOME/bin
export CATALINA_BASE=$SQOOP_HOME/server
export LOGDIR=$SQOOP_HOME/logs/ - 生效环境变量的配置
- source 配置文件名
修改sqoop配置:
vi server/conf/sqoop.properties
将org.apache.sqoop.submission.engine.mapreduce.configuration.directory后面hadoop的位置修改为自己安装的hadoop配置文件位置,我的为:/home/hadoop/app/hadoop/修改sqoop读取hadoop的jar包的路径 vi /sqoop/server/conf/catalina.properties
将common.loader行后的/usr/lib/hadoop/lib/.jar改成自己的hadoop jar 包目录,我的为:
/home/hadoop/app/hadoop/share/hadoop/common/.jar,
/home/hadoop/app/hadoop/share/hadoop/common/lib/.jar,
/home/hadoop/app/hadoop/share/hadoop/hdfs/.jar,
/home/hadoop/app/hadoop/share/hadoop/hdfs/lib/.jar,
/home/hadoop/app/hadoop/share/hadoop/mapreduce/.jar,
/home/hadoop/app/hadoop/share/hadoop/mapreduce/lib/.jar,
/home/hadoop/app/hadoop/share/hadoop/tools/.jar,
/home/hadoop/app/hadoop/share/hadoop/tools/lib/.jar,
/home/hadoop/app/hadoop/share/hadoop/yarn/.jar,
/home/hadoop/app/hadoopshare/hadoop/yarn/lib/*.jar
注意: 在修改common.loader的过程中, 不能换行
本步骤的另外的一种方法是: 直接将上诉的包 拷贝到$SQOOP_HOME/server/lib文件夹内部- 将mysql的连接jar包拷贝的$SQOOP_HOME/lib文件夹中(lib文件夹需要自己创建)到此sqoop就基本配置完成可以直接运行.
下面是,对sqoop2的配置文件进行配置
1、修改$SQOOP_HOME/server/conf/catalina.properties文件中的common.loader属性,在其后增加(写到一行):
$HADOOP_HOME/share/hadoop/common/*.jar,
$HADOOP_HOME/share/hadoop/common/lib/*.jar,
$HADOOP_HOME/share/hadoop/yarn/*.jar,
$HADOOP_HOME/share/hadoop/hdfs/*.jar,
$HADOOP_HOME,/share/hadoop/mapreduce/*.jar
[hadoop@bigdatamaster conf]$ pwd
/home/hadoop/app/sqoop/server/conf
[hadoop@bigdatamaster conf]$ ll
total
-rw-r--r-- hadoop hadoop May catalina.policy
-rw-r--r-- hadoop hadoop Apr catalina.properties
-rw-r--r-- hadoop hadoop May context.xml
-rw-r--r-- hadoop hadoop May logging.properties
-rw-r--r-- hadoop hadoop Apr server.xml
-rw-r--r-- hadoop hadoop Apr sqoop_bootstrap.properties
-rw-r--r-- hadoop hadoop Apr sqoop.properties
-rw-r--r-- hadoop hadoop May tomcat-users.xml
-rw-r--r-- hadoop hadoop May web.xml
[hadoop@bigdatamaster conf]$ vim catalina.properties
$HADOOP_HOME/share/hadoop/common/*.jar,$HADOOP_HOME/share/hadoop/common/lib/*.jar,$HADOOP_HOME/share/hadoop/yarn/*.jar,$HADOOP_HOME/share/hadoop/hdfs/*.jar,$HADOOP_HOME,/share/hadoop/mapreduce/*.jar
2、修改$SQOOP_HOME/server/conf/sqoop.properties文件org.apache.sqoop.submission.engine.mapreduce.configuration.directory属性,指向本机hadoop配置目录。
[hadoop@bigdatamaster conf]$ pwd
/home/hadoop/app/sqoop/server/conf
[hadoop@bigdatamaster conf]$ ll
total
-rw-r--r-- hadoop hadoop May catalina.policy
-rw-r--r-- hadoop hadoop May : catalina.properties
-rw-r--r-- hadoop hadoop May context.xml
-rw-r--r-- hadoop hadoop May logging.properties
-rw-r--r-- hadoop hadoop Apr server.xml
-rw-r--r-- hadoop hadoop Apr sqoop_bootstrap.properties
-rw-r--r-- hadoop hadoop Apr sqoop.properties
-rw-r--r-- hadoop hadoop May tomcat-users.xml
-rw-r--r-- hadoop hadoop May web.xml
[hadoop@bigdatamaster conf]$ vim sqoop.properties
# Hadoop configuration directory
org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/home/hadoop/app/hadoop/conf/
3、$SQOOP_HOME/server/conf/server.xml是Tomcat的配置文件,端口什么的可以在这个文件设置
这里,我暂时不设置。
4、复制mysql-connector-java-5.1.21.jar到$SQOOP_HOME/server/lib/下
[hadoop@bigdatamaster lib]$ pwd
/home/hadoop/app/sqoop2-1.99.-cdh5.5.4/server/lib
[hadoop@bigdatamaster lib]$ ls
annotations-api.jar catalina-ha.jar catalina-tribes.jar el-api.jar jasper.jar servlet-api.jar tomcat-coyote.jar tomcat-i18n-es.jar tomcat-i18n-ja.jar
catalina-ant.jar catalina.jar ecj-4.3..jar jasper-el.jar jsp-api.jar sqoop-tomcat-1.99.-cdh5.5.4.jar tomcat-dbcp.jar tomcat-i18n-fr.jar
[hadoop@bigdatamaster lib]$ rz [hadoop@bigdatamaster lib]$ ls
annotations-api.jar catalina.jar el-api.jar jsp-api.jar sqoop-tomcat-1.99.-cdh5.5.4.jar tomcat-i18n-es.jar
catalina-ant.jar catalina-tribes.jar jasper-el.jar mysql-connector-java-5.1..jar tomcat-coyote.jar tomcat-i18n-fr.jar
catalina-ha.jar ecj-4.3..jar jasper.jar servlet-api.jar tomcat-dbcp.jar tomcat-i18n-ja.jar
[hadoop@bigdatamaster lib]$
Sqoop2全部配置好之后,按照如下的顺序来
1、启动Sqoop2的server(我这里做个最简单的,在bigdatamaster上)。启动sqoop服务
$SQOOP_HOME/bin/sqoop.sh server start
[hadoop@bigdatamaster hadoop]$ cd $SQOOP_HOME
[hadoop@bigdatamaster sqoop]$ pwd
/home/hadoop/app/sqoop
[hadoop@bigdatamaster sqoop]$ $SQOOP_HOME/bin/sqoop.sh server start
Sqoop home directory: /home/hadoop/app/sqoop
Setting SQOOP_HTTP_PORT:
Setting SQOOP_ADMIN_PORT:
Using CATALINA_OPTS:
Adding to CATALINA_OPTS: -Dsqoop.http.port= -Dsqoop.admin.port=
Using CATALINA_BASE: /home/hadoop/app/sqoop/server
Using CATALINA_HOME: /home/hadoop/app/sqoop/server
Using CATALINA_TMPDIR: /home/hadoop/app/sqoop/server/temp
Using JRE_HOME: /home/hadoop/app/jdk
Using CLASSPATH: /home/hadoop/app/sqoop/server/bin/bootstrap.jar
[hadoop@bigdatamaster sqoop]$ jps
QuorumPeerMain
NameNode
Bootstrap
Jps
SecondaryNameNode
ResourceManager
[hadoop@bigdatamaster sqoop]$
jsp命令看到Bootstrap进程。
2、启动Sqoop2的client(我这里做个最简单的,在bigdatamaster上),进入客户端交互模式。进入sqoop控制台
$SQOOP_HOME/bin/sqoop.sh client
[hadoop@bigdatamaster sqoop]$ pwd
/home/hadoop/app/sqoop
[hadoop@bigdatamaster sqoop]$ $SQOOP_HOME/bin/sqoop.sh client
Sqoop home directory: /home/hadoop/app/sqoop
May , :: PM java.util.prefs.FileSystemPreferences$ run
INFO: Created user preferences directory.
Sqoop Shell: Type 'help' or '\h' for help. sqoop:>
3、在Sqoop2的client连接Sqoop2的server 。 连接服务器
sqoop:> set server --host bigdatamaster --port --webapp sqoop
sqoop:000> set server --host localhost --port 12000 --webapp sqoop
sqoop:000> show version --all
当看到show version -all正确的显示 就说明了Sqoop2的client连接上了Sqoop2的服务器。
show version --all 显示服务器、客户端的版本信息,如果server显示错误,
重启一下 server./sqoop.sh server stop
[hadoop@bigdatamaster sqoop]$ pwd
/home/hadoop/app/sqoop
[hadoop@bigdatamaster sqoop]$ $SQOOP_HOME/bin/sqoop.sh client
Sqoop home directory: /home/hadoop/app/sqoop
May , :: PM java.util.prefs.FileSystemPreferences$ run
INFO: Created user preferences directory.
Sqoop Shell: Type 'help' or '\h' for help. sqoop:> set server --host bigdatamaster --port --webapp sqoop
Server is set successfully
sqoop:> show version --all
client version:
