Question

我正在尝试春季批量字数统计程序并面临这样的版本问题：

ERROR [org.springframework.batch.core.step.AbstractStep] - <Encountered an error executing the step>
java.lang.IncompatibleClassChangeError: Found interface org.apache.hadoop.mapreduce.Counter, but class was expected

我使用Cloudera Hadoop2 cdh4.5.0 和Spring hadoop版本 1.0.1.RELEASE 。由于Spring批次与 hadoop cdh4 兼容，我无法确定确切的问题。

我的依赖树如下所示。

此外，是否因为重复的依赖性而导致出现任何错误？

Answer 1

您应该将1.0.2.RELEASE-cdh4版本与Cloudera CDH4一起使用 - 这些发行版特定版本可在Spring存储库中找到：

<repository>
  <id>spring-releases</id>
  <name>Spring Release Repository</name>
  <url>http://repo.spring.io/libs-release</url>
</repository>

版本与Spring批次和cloudera hadoop之间不兼容
