打开META-INF目录，将*.SF,*.DSA,*.RSA文件删除，即可。应为有些包有签名，导致错误。

在Linux系统下直接运行：

hadoop@master:/usr/local/hadoop/spark/spark-data$ sudo zip -d project.jar META-INF/*.RSA META-INF/*.DSA META-INF/*.SF
[sudo] hadoop 的密码：
zip warning: name not matched: META-INF/*.RSA
deleting: META-INF/BCKEY.SF
deleting: META-INF/BCKEY.DSA
deleting: META-INF/DUMMY.SF
deleting: META-INF/DUMMY.DSA
deleting: META-INF/DEV.SF
deleting: META-INF/DEV.DSA
hadoop@master:/usr/local/hadoop/spark/spark-data$

即可！！！
