Java 使用cloudera hadoop maven依赖项时出现异常
我试图在eclipse中运行一个mapreduce程序，使用Windows7中pom.xml中的ClouderaHadoop maven依赖项。当在pom.xml中使用2.0.0-cdh4.0.0依赖版本时，程序工作正常，但当我将版本更改为2.0.0-cdh4.6.0时，它会抛出以下警告消息 警告fs.LocalDirAllocator$AllocatorPerContext:未能创建 /tmp/hadoop-Abhijeet/mapred/local/file:/tmp/hadoop-Abhijeet/mapred/local/localRunner/Abhijeet/job\u local83327001\u 0001/trunt\u local83327001\u 0001\u m\u000001\u 0 请注意，文件路径的模式在路径之间是异常文件：/ 最终，它抛出了一个异常，随后Java 使用cloudera hadoop maven依赖项时出现异常,java,hadoop,cloudera,Java,Hadoop,Cloudera,我试图在eclipse中运行一个mapreduce程序，使用Windows7中pom.xml中的ClouderaHadoop maven依赖项。当在pom.xml中使用2.0.0-cdh4.0.0依赖版本时，程序工作正常，但当我将版本更改为2.0.0-cdh4.6.0时，它会抛出以下警告消息 警告fs.LocalDirAllocator$AllocatorPerContext:未能创建 /tmp/hadoop-Abhijeet/mapred/local/file:/tmp/hadoop-Abhi
