我尝试设置 3 个队列。为此，我配置了 CapacityScheduler.xml，如下所示。但在此之后，jobtracker 将关闭。我也将这些队列的名称添加到了 mapred-site.xml。任何人都知道原因。

enter code here

*<!-- queue: BatchJobs-Queue -->
<property>

  <value>70</value>
</property>

您的工作跟踪日志的输出是什么？

假设您正在运行 linux，请尝试运行以下命令：

ls -lrt /var/log/hadoop/mapred/ | grep jobtracker | tail -n1 | awk '{print $9}' | xargs -I{} tail -n40 /var/log/hadoop/mapred/{}
