我在一个aws emr集群上，我刚刚站起来，有一个scala文件编译，还有一个我想编译成程序集的。但是，当我发布sbt程序集时，我遇到了重复数据消除错误。
每https://medium.com/@tedherman/compile-scala-on-emr-cb77610559f0我最初有一个lib到usr lib spark jars的符号链接；

ln -s /usr/lib/spark/jars lib

尽管我注意到我的代码通过了sbt编译，不管有没有这个。但是，我不知道为什么/如何解决sbt程序集重复错误。我还将注意到，我按照本文在引导操作中安装了sbt。
符号链接在
有些重复数据消除似乎是清晰的精确重复数据；例子：

[error] deduplicate: different file contents found in the following:
[error] /home/hadoop/.ivy2/cache/org.apache.parquet/parquet-jackson/jars/parquet-jackson-1.10.1.jar:shaded/parquet/org/codehaus/jackson/util/CharTypes.class
[error] /usr/lib/spark/jars/parquet-jackson-1.10.1-spark-amzn-1.jar:shaded/parquet/org/codehaus/jackson/util/CharTypes.class

另一些似乎是相互竞争的版本；

[error] deduplicate: different file contents found in the following:
[error] /home/hadoop/.ivy2/cache/org.apache.spark/spark-core_2.11/jars/spark-core_2.11-2.4.3.jar:org/spark_project/jetty/util/MultiPartOutputStream.class
[error] /usr/lib/spark/jars/spark-core_2.11-2.4.5-amzn-0.jar:org/spark_project/jetty/util/MultiPartOutputStream.class

我不明白为什么会有相互竞争的版本；或者，如果他们是默认的这样或我做了什么介绍他们。
没有符号链接
我想如果我去掉这个，我的问题会少一些；虽然我仍然有欺骗（只是少）；

[error] deduplicate: different file contents found in the following:
[error] /home/hadoop/.ivy2/cache/org.apache.hadoop/hadoop-yarn-api/jars/hadoop-yarn-api-2.6.5.jar:org/apache/hadoop/yarn/factory/providers/package-info.class
[error] /home/hadoop/.ivy2/cache/org.apache.hadoop/hadoop-yarn-common/jars/hadoop-yarn-common-2.6.5.jar:org/apache/hadoop/yarn/factory/providers/package-info.class

考虑到一个是hadoop-yarn-api-2.6.5.jar，另一个是hadoop-yarn-common-2.6.5.jar，我不明白为什么上面的内容是重复的。不同的名字那为什么要被骗？
其他的似乎是版本；

[error] deduplicate: different file contents found in the following:

有些文件名相同，但路径/jar不同。。。

和这些一样。。。
