Sqoop 1.99.3 with hadoop-2.3.0 使用1

zxcvb12

　　使用 sqoop-1.99.3-bin-hadoop200
配置如下
1.解压
tar -xvf sqoop--bin-hadoop.tar.gz
2.加入配置文件 server/conf/catalina.properties 中的common.loader 属性加入hadoop2的lib
因为hadoop_home 下的lib是空的 所以指向 
/home/hadoop-2.3.0/share/hadoop/common/*.jar
/home/hadoop-2.3.0/share/hadoop/common/lib/*.jar
/home/hadoop-2.3.0/share/hadoop/yarn/*.jar
/home/hadoop-2.3.0/share/hadoop/hdfs/*.jar
/home/hadoop-2.3.0/share/hadoop/mapreduce/*.jar
启动后发现有问题， 查看 sqoop_home/server/log 报错了

Mar 19, 2014 8:08:55 AM org.apache.catalina.core.StandardContext listenerStart
SEVERE: Exception sending context initialized event to listener instance of class org.apache.sqoop.server.ServerInitializer
java.lang.RuntimeException: Failure in server initialization

找到了 server/conf/sqoop.properties 里面的属性要改成

# Hadoop configuration directory
#org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/etc/hadoop/conf/
 org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/home/hadoop-2.3.0/etc/hadoop
 
查看log 没有错误.进入[size=1em]./bin/sqoop.sh client
show version --all 查看有没错误。再次确认启动成功.

建立一个connection 根据提示输入
create connection --cid 1 （connection id为1）
Creating connection for connector with id 1
Please fill following values to create new connection object
Name: VPRCFJTBCOBI-02

　　查看下成果
　　show connector
　　+----+------------------------+---------+------------------------------------------------------+
　　| Id |          Name                    | Version |                        Class                         |
　　+----+------------------------+---------+------------------------------------------------------+
　　| 1  | generic-jdbc-connector | 1.99.3  | org.apache.sqoop.connector.jdbc.GenericJdbcConnector |
　　show connection

PS 建错了connection 就删了 [size=1em]delete connection --xid 1 也可以[size=1em]update connection --xid 1
