java操作sqoop在本地测试正常打包发布到阿里云服务器报错

在做项目时，把sqoop和mapreduce集成到springboot中做数据抽取和计算，并打成jar包上传到服务器，项目是使用eureka进行注册提供服务，父项目下创建子模块，通过maven的package打包子模块。
通过以下命令在服务器运行

# nohup和&组合在后台运行 运行时会在当前目录下生成一个nohup.out日志文件
[root@fda ~]# nohup java -jar XXX.jar &
 
Sqoop版本1.4.7
Hadoop版本2.7.7
当进行sqoop的数据抽取时报错信息如下

这里一共有两个问题第一个问题

这是由于阿里云的环境变量没有配置完整Hadoop的环境变量。在服务器的 /etc/profile 中添加如下配置
#Hadoop环境变量

[root@fda ~]# vim /etc/profile
#添加下面的内容
export HADOOP_HOME=/opt/module/Hadoop/hadoop-2.7.7
export HADOOP_MAPRED_HOME=$HADOOP_HOME
export HADOOP_COMMON_HOME=$HADOOP_HOME
export HADOOP_HDFS_HOME=$HADOOP_HOME
export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop
export HADOOP_LOG_DIR=$HADOOP_HOME/logs
export YARN_HOME=$HADOOP_HOME
export YARN_CONF_DIR=$HADOOP_HOME/etc/hadoop
export YARN_LOG_DIR=$HADOOP_LOG_DIR
export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin 
第一个问题解决。
第二个问题是

import com.cloudera.sqoop.lib.BooleanParser; 
报的sqoop的找不到sqoop-1.4.7.jar下面的类，打开打成的可执行jar包，在BOOT-INFlib下确实有sqoop-1.4.7.jar，找了好几天最终发现问题，是因为打包的原因，但是又找不到怎样去打包，索性直接把原来的后台项目架构改成了单体的springboot项目，打成war包部署到服务器，问题解决。

原来打包问题待进一步研究……如果小伙伴有解决方案，请与我分享一下，感谢！！！
