2016年8月27日，解决sqoop先下载的是sqoop1.99.7，结果配置的时候，出现了没有server/conf目录，以及启动时出现无法配置错误
./bin/sqoop.sh server start
yq@ubuntu:/opt/sqoop-1.99.7$ ./bin/sqoop.sh server start
Setting conf dir: ./bin/../conf

解决办法是下载sqoop1.99.3，然后哪找如下配置，搞掂：
[*] 2.解压文件到工作目录:
[*] hadoop@hadoopMaster:$ sudo tar -xvf /opt/hn/hadoop_family/sqoop-1.99.3-bin-hadoop200.tar.gz
[*] hadoop@hadoopMaster:mv /opt/hn/hadoop_family/sqoop-1.99.3-bin-hadoop200 /usr/local/sqoop
[*] 3.修改环境变量：
[*] hadoop@hadoopMaster:~$ vim /etc/profile
[*] 添加如下内容：
[*] #sqoop
[*] export SQOOP_HOME=/usr/sqoop-1.99.3
[*] export PATH=$SQOOP_HOME/bin:$PATH
[*] export CATALINA_HOME=$SQOOP_HOME/server
[*] export LOGDIR=$SQOOP_HOME/logs
[*] 保存退出即时生效：
[*] source /etc/profile
[*] 4.修改sqoop配置：
[*] hadoop@hadoopMaster:~$ vim /usr/local/sqoop/server/conf/sqoop.properties
[*] #修改指向我的hadoop的配置文件目录
[*] org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/usr/local/hadoop-2.6.2/etc/hadoop
[*] #把hadoop目录下的jar包都引进来
[*] hadoop@hadoopMaster:~$ vim /usr/local/sqoop/server/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
[*] 5.下载mysql驱动包
[*] mysql-connector-java-5.1.16-bin.jar
[*] 6.启动/停止sqoop200
[*] hadoop@hadoopMaster:/usr/local/sqoop/bin$ ./sqoop.sh server start/stop
跑起来试试：
dyq@ubuntu:/opt/sqoop-1.99.3$./bin/sqoop.sh server start
Sqoop home directory: /opt/sqoop-1.99.3
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: /opt/sqoop-1.99.3/server
Using CATALINA_HOME: /opt/sqoop-1.99.3/server
Using CATALINA_TMPDIR: /opt/sqoop-1.99.3/server/temp
Using JRE_HOME: /usr/java/jdk1.7.0_79/jre
