Apache spark 我在尝试在emr上使用oozie执行spark submit时遇到以下错误

我正在群集模式下运行。apacheds-kerberos-codec-2.0.0-M15.jar存在于oozie/share/lib/lib*/spark和oozie/share/lib/lib*/oozie中的多个位置。这是环境问题吗

ava.lang.IllegalArgumentException: Attempt to add (hdfs://ip-172-20-10-53.ec2.internal:8020/user/oozie/share/lib/lib_20170208121307/oozie/apacheds-kerberos-codec-2.0.0-M15.jar) multiple times to the distributed cache.

看起来oozie sharelib和spark sharelib目录共享相同的JAR，运行spark工作流会导入这两个目录，而hadoop-3代码库不喜欢这两个目录

我不得不重新组织oozie sharelib目录，使其只包含oozie特定的JAR，这样oozie和spark sharelib目录之间就不会有重复：

export HADOOP_USER_NAME=oozie
hdfs dfs -mv /user/oozie/share/lib/lib_20170222143042/oozie /user/oozie/share/lib/lib_20170222143042/oozie.old
hdfs dfs -mkdir /user/oozie/share/lib/lib_20170222143042/oozie
hdfs dfs -cp /user/oozie/share/lib/lib_20170222143042/oozie.old/oozie-hadoop-utils-hadoop-2-4.3.0.jar /user/oozie/share/lib/lib_20170222143042/oozie
hdfs dfs -cp /user/oozie/share/lib/lib_20170222143042/oozie.old/oozie-sharelib-oozie-4.3.0.jar /user/oozie/share/lib/lib_20170222143042/oozie

这解决了从oozie运行spark工作流的直接问题，但我不确定这是否会影响非spark工作流。

我有一个oozie作业，它启动了spark作业，在Amazon EMR中运行。当EMR Hadoop安装程序有一个主实例和一个从实例时，我得到了相同的错误。当我将从属实例的数量增加到两个时，一切都按预期进行。

欢迎使用堆栈溢出！你可以选择第一个，学习一个好的问题，然后创造一个新的答案。这使我们更容易帮助您。您是否使用Hadoop-3发行版代码库。Hadoop 3不再允许在分布式缓存中使用重复的文件名，即使它们是同一个文件。
