我正在运行我的eclipse中的WordCount程序。我尝试使用Hadoop1。X，它运行良好。在hadoop2.x上运行时遇到问题
我试过了1)将所有XML添加到我的类路径中。2)还尝试了conf.set()，在conf对象中设置XML属性。
同样在日志中它说:-No logs available for container container_1394042163908_0573_01_000001
Application application_1394042163908_0573 failed 2 times due to AM Container for appattempt_1394042163908_0573_000002 exited with exitCode: 1 due to: Exception from container-launch:

我已经找到了这个问题，有一个jira:https://issues.apache.org/jira/browse/MAPREDUCE-5655
我刚刚添加了YARNRunner.java &java到我的项目。它还需要在windows框上的mapred-site.xml中添加以下属性，以便作业启动器知道作业运行器将是linux:
<property>
<name>mapred.remote.os</name>
<value>Linux</value>
<description>Remote MapReduce framework's OS, can be either Linux or Windows</description>
</property>
和MapReduce现在运行良好。
也复制org.apache.hadoop.util.Shell.java到你的项目中。
您可以注释掉下面的行，以删除winutils.exe错误。
抛出新的IOException("Could not locate executable " + fulllexename + " in Hadoop二进制文件");
