我最近升级到 clodera4b1 。升级之前，mapreduce 作业运行良好，但现在当我执行任何 mapreduce 程序时，出现以下错误：

命令运行：

hadoop jar /usr/lib/hadoop/hadoop-mapreduce-examples-0.23.0-cdh4b1.jar grep *.xml /user/out/ 'dfs'


12/04/10 19:23:15 INFO mapreduce.Cluster: Failed to use org.apache.hadoop.mapred.LocalClientProtocolProvider due to error: Invalid "mapreduce.jobtracker.address" configuration value for LocalJobRunner : "dev-xxx:yyyy"

对于我的自定义映射作业，我在编译 jar 文件时将库文件更改为新文件，但没有成功

我们有同样的异常，原因是我们在 pom 文件中有错误的依赖项。我们指向的是用于 yarn 的 hadoop-client 版本 2.0.0-cdh4.0.0，但我们使用的是 MRv1，所以我们应该指向 2.0.0-mr1-cdh4.0.0。您的依赖项中不应有任何纱线 jar 文件。

参考
