Hadoop2.2.0环境下Sqoop1.99.3安装

本文转载自http://blog.csdn.net/liuwenbo0920/article/details/40504045

1.安装准备工作：

已经装好的hadoop环境是hadoop 2.2.0
下载的sqoop安装包（注意是hadoop200）

下载sqoop  wget  http://mirrors.cnnic.cn/apache/sqoop/1.99.6/sqoop-1.99.3-bin-hadoop200.tar.gz

2.解压文件到工作目录:

将sqoop解压到目标目录，我的是 /opt/soft/sqoop-1.99.3-bin-hadoop200

配置环境变量：

export SQOOP_HOME=/opt/soft/sqoop-1.99.3-bin-hadoop200
export CATALINA_HOME=$SQOOP_HOME/server
export LOGDIR=$SQOOP_HOME/logs
export PATH=$SQOOP_HOME/bin:$PATH

保存退出即时生效：

source /etc/profile

3.修改sqoop配置：
 vi   /opt/soft/sqoop-1.99.3-bin-hadoop200/server/conf/sqoop.properties 

在文件中找到org.apache.sqoop.submission.engine.mapreduce.configuration.directory，用Hadoop的配置文件目录赋值，最终效果如下：

org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/opt/soft/hadoop-2.2.0/etc/hadoop

4.修改配置文件：
修改配置文件catalina.properties：
vim $SQOOP_HOME/server/conf/catalina.properties

在文件中找到common.loader，在其后添加hadoop相关jar包路径，最终效果如下

common.loader=${catalina.base}/lib,
${catalina.base}/lib/*.jar,
${catalina.home}/lib,
${catalina.home}/lib/*.jar,
${catalina.home}/../lib/*.jar,
/opt/soft/hadoop-2.2.0/share/hadoop/common/*.jar,
/opt/soft/hadoop-2.2.0/share/hadoop/common/lib/*.jar,
/opt/soft/hadoop-2.2.0/share/hadoop/hdfs/*.jar,
/opt/soft/hadoop-2.2.0/share/hadoop/hdfs/lib/*.jar,
/opt/soft/hadoop-2.2.0/share/hadoop/mapreduce/*.jar,
/opt/soft/hadoop-2.2.0/share/hadoop/mapreduce/lib/*.jar,
/opt/soft/hadoop-2.2.0/share/hadoop/tools/*.jar,
/opt/soft/hadoop-2.2.0/share/hadoop/tools/lib/*.jar,
/opt/soft/hadoop-2.2.0/share/hadoop/yarn/*.jar,
/opt/soft/hadoop-2.2.0/share/hadoop/yarn/lib/*.jar,
/opt/soft/hadoop-2.2.0/share/hadoop/httpfs/tomcat/lib/*.jar

安装中遇到的问题： 

我在启动show version --all时，出现GET http://localhost:12000/sqoop/version returned a response status of 404 Not Found

后来查看日志，发现时log4j的原因。

由于在catalina.properties配置文件的common.loader属性中配置引入了所有的hadoop相关jar包，而hadoop的lib目录下是有log4j包的，只是版本和sqoop自带的log4j不一致。
我们需要将/opt/soft/sqoop-1.99.3-bin-hadoop200/server/webapps/sqoop/WEB-INF/lib目录下的log4j-1.2.16.jar移除即可。

发现还是不能解决，日志仍然抱  java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory ，于是手动将hadoop的jar包全部copy出来，

然后复制到/opt/soft/sqoop-1.99.3-bin-hadoop200/server/webapps/sqoop/WEB-INF/lib目录下，还原common.loader中修改的内容，然后启动就好了。

5.下载mysql驱动包

mysql-connector-java-5.1.16-bin.jar   第三步，jar包相关工作：
我拷贝到了两个目录  $SQOOP_HOME/server/lib  下

6.启动/停止sqoop200 

./bin/sqoop.sh server start

./bin/sqoop.sh server stop

查看启动日志：

hadoop@hadoopMaster:/usr/local/sqoop/server/logs$ vim catalina.out 

7.进入客户端交互目录

bin/sqoop.sh client
