Sqoop1.9.x安装

环境：CentOS 6.5 、Hadoop2.5.2 、sqoop1.99.3

1.9.x版本的sqoop分为服务器和客户端两个部分。服务端可以独立安装hadoop集群的任意一台节点，甚至此节点的hadoop服务不必处于运行状态；在启动服务端后任意安装客户端即可。在新的架构下，命令的执行全部放在了客户端。

1.下载sqoop

[grid@hadoop6 ~]$ wget http://archive.apache.org/dist/sqoop/1.99.3/sqoop-1.99.3-bin-hadoop200.tar.gz
[grid@hadoop6 ~]$ tar -zxf sqoop-1.99.3-bin-hadoop200.tar.gz
[grid@hadoop6 ~]$ mv sqoop-1.99.3-bin-hadoop200 sqoop-1.99.3

2.修改环境变量

[grid@hadoop6 ~]$ vi .bash_profile
export SQOOP_HOME=/home/grid/sqoop-1.99.3
export PATH=$SQOOP_HOME/bin:$PATH
export CATALINA_BASE=$SQOOP_HOME/server
export LOGDIR=$SQOOP_HOME/logs
[grid@hadoop6 ~]$ source .bash_profile

附：hadoop的环境变量设置
export HADOOP_PREFIX=/home/grid/hadoop-2.5.2
export HADOOP_COMMON_HOME=$HADOOP_PREFIX
export HADOOP_HDFS_HOME=$HADOOP_PREFIX
export HADOOP_MAPRED_HOME=$HADOOP_PREFIX
export HADOOP_YARN_HOME=$HADOOP_PREFIX
export HADOOP_CONF_DIR=$HADOOP_PREFIX/etc/hadoop
export PATH=$PATH:$HADOOP_PREFIX/bin:$HADOOP_PREFIX/sbin

3.修改catalina.properties
找到common.loader行，删除hadoop所有jar路径，加入本机hadoop2的jar路径
hadoop-2.x.x/share/hadoop/common/*.jar
hadoop-2.x.x/share/hadoop/common/lib/*.jar
hadoop-2.x.x/share/hadoop/yarn/*.jar
hadoop-2.x.x/share/hadoop/yarn/lib/*.jar
hadoop-2.x.x/share/hadoop/hdfs/*.jar
hadoop-2.x.x/share/hadoop/hdfs/lib/*.jar
hadoop-2.x.x/share/hadoop/mapreduce/*.jar
hadoop-2.x.x/share/hadoop/mapreduce/lib/*.jar
本次实验示例：

[grid@hadoop6 conf]$ pwd
/home/grid/sqoop-1.99.3/server/conf
[grid@hadoop6 conf]$ vim catalina.properties 
common.loader=${catalina.base}/lib,${catalina.base}/lib/*.jar,${catalina.home}/lib,${catalina.home}/lib/*.jar,${catalina.home}/../lib/*.jar,/home/grid/hadoop-2.5.2/share/hadoop/common/*.jar,/home/grid/hadoop-2.5.2/share/hadoop/common/lib/*.jar,/home/grid/hadoop-2.5.2/share/hadoop/hdfs/*.jar,/home/grid/hadoop-2.5.2/share/hadoop/hdfs/lib/*.jar,/home/grid/hadoop-2.5.2/share/hadoop/mapreduce/*.jar,/home/grid/hadoop-2.5.2/share/hadoop/mapreduce/lib/*.jar,/home/grid/hadoop-2.5.2/share/hadoop/tools/lib/*.jar,/home/grid/hadoop-2.5.2/share/hadoop/yarn/*.jar,/home/grid/hadoop-2.5.2/share/hadoop/yarn/lib/*.jar,/home/grid/hadoop-2.5.2/share/hadoop/httpfs/tomcat/lib/*.jar

如果还需要导入hive或hbase，对应的jar包也需要加入

由于添加的jar包中包含了log4j.jar，为了防止jar包冲突，删除sqoop中的log4j.jar

[grid@hadoop6 sqoop-1.99.3]$ mv ./server/webapps/sqoop/WEB-INF/lib/log4j-1.2.16.jar ./server/webapps/sqoop/WEB-INF/lib/log4j-1.2.16.jar.bak

4.修改sqoop.properties
指定hadoop配置文件路径，修改 内嵌元数据库deby的库名为SQOOP

[grid@hadoop6 conf]$ vim sqoop.properties
org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/home/grid/hadoop-2.5.2/etc/hadoop
org.apache.sqoop.repository.jdbc.url=jdbc:derby:@BASEDIR@/repository/SQOOP;create=true

替换@LOGDIR@ 和@BASEDIR@ ：

[grid@hadoop6 conf]$ sed -i 's/@BASEDIR@/\/home\/grid\/sqoop-1.99.3\/base/g' sqoop.properties
[grid@hadoop6 conf]$ sed -i 's/@LOGDIR@/\/home\/grid\/sqoop-1.99.3\/logs/g' sqoop.properties

5.拷贝数据库驱动包到$SQOOP_HOME/lib目录下（若目录不存在则首先创建目录）

检测安装是否成功（1.99.4以上版本支持）：
a.先赋可执行权限：

[grid@hadoop6 sqoop-1.99.4]$ chmod ug+x ./bin/*

b.再检测：

[grid@hadoop6 sqoop-1.99.4]$ sqoop-tool verify

6.启动sqoop服务
启动hadoop
[grid@hadoop6 ~]$ sh $HADOOP_PREFIX/sbin/start-dfs.sh
[grid@hadoop6 ~]$ sh $HADOOP_PREFIX/sbin/start-yarn.sh

启动sqoop服务

[grid@hadoop6 ~]$ sqoop.sh server start

7.使用sqoop客户端 

[grid@hadoop6 logs]$ sqoop.sh client
Sqoop home directory: /home/grid/sqoop-1.99.3

看到有一个警告：Can't connect to the database with given credentials: Access denied for user 'grid'@'%' to database 'sqoop' ，这个是MySql的连接权限问题，通过以下方法解决：

mysql> GRANT ALL PRIVILEGES ON sqoop.* TO 'grid'@'%';

查看Job状态：

sqoop:000> status job --jid 1 

发现Job出错：Caused by: Exception: java.io.IOException Message: java.net.ConnectException: Call From hadoop6/192.168.0.108 to hadoop4:10020 failed on connection exception: java.net.ConnectException: 拒绝连接
经查是jobhistory没有启动导致的，启动jobhistory：

[grid@hadoop4 ~]$ mr-jobhistory-daemon.sh start historyserver
starting historyserver, logging to /home/grid/hadoop-2.5.2/logs/mapred-grid-historyserver-hadoop4.out

遇到的问题：同样的步骤，使用sqoop1.99.4、sqoop1.99.5，都安装失败，这里请大伙指点，启动报错信息如下
