Question

我是hadoop世界的新人。我在Linux中设置了一个hadoop集群，我尝试从windows运行mapreduce作业。我wordcount示例工作查找，但当我尝试运行我自己写的另一份工作时，我有这个错误：

有人能帮助我吗？

  <property>
    <name>mapred.remote.os</name>
    <value>Linux</value>
    <description>Remote MapReduce framework's OS, can be either Linux or Windows</description>
  </property>
  <property>
    <name>mapreduce.app-submission.cross-platform</name>
    <value>true</value>
  </property>
