1.之前安装了1.99.5版本，不是很好用，重新换了个版本
2.下载1.99.5安装包
3.目录下sqoop-1.99.5/server/conf 文件sqoop.properties，修改配置文件

org.apache.sqoop.submission.engine.mapreduce.configuration.directory=/opt/soft/hadoop-2.7.5/etc/hadoop/conf/

4.修改catalina.properties文件

common.loader=${catalina.base}/lib,${catalina.base}/lib/*.jar,${catalina.home}/lib,${catalina.home}/lib/*.jar,${catalina.home}/../lib/*.jar,/opt/soft/hadoop-2.7.5/share/hadoop/common/*.jar,/opt/soft/hadoop-2.7.5/share/hadoop/common/lib/*.jar,/opt/soft/hadoop-2.7.5/share/hadoop/hdfs/*.jar,/opt/soft/hadoop-2.7.5/share/hadoop/hdfs/lib/*.jar,/opt/soft/hadoop-2.7.5/share/hadoop/mapreduce/*.jar,/opt/soft/hadoop-2.7.5/share/hadoop/mapreduce/bin/*.jar,/opt/soft/hadoop-2.7.5/share/hadoop/tools/*.jar,/opt/soft/hadoop-2.7.5/share/hadoop/tools/bin/*.jar,/opt/soft/hadoop-2.7.5/share/hadoop/yarn/*.jar,/opt/soft/hadoop-2.7.5/share/hadoop/yarn/bin/*.jar
