我有一个以mapreduce模式运行的猪脚本，该脚本一直在收到我无法修复的持续错误。该脚本催生了多个MapReduce应用程序；运行几个小时后，其中一个应用程序寄存器是成功的，但返回以下诊断消息：
成功犯下后，我们坠毁了。恢复。
导致故障的步骤正在尝试通过大约100GB的数据集执行排名，从以前的脚本中划分约1000个MapReduce输出文件。但是我也收到了试图执行大型Hash_join操作的其他脚本的同样错误。
挖掘日志，我找到了以下内容，这似乎也表明工作成功，但随后收到了一个错误：

我尝试了几种解决mapReduce.counters.limitexceededexception的方法。我已经修改了Ambari中的MapReduce配置，将mapReduce.job.counters.max设置为20000(只是为了测试该问题的解决方案，而不是将其留在那里(。我还尝试使用set mapreduce.job.counters.max 10000;行启动猪脚本，以覆盖最大计数器。两者似乎都有任何影响。该错误仍然显示限制为120。
我很困惑为什么更改最大计数器配置似乎没有影响。我可能缺少一些相关的配置吗？还是此错误消息可能不准确，或者是表示不同问题的症状？
更新：我发现了许多与此问题有关的Apache MapReduce Jira门票；似乎这是一个现有的错误。我已经转而在Tez上运行我的工作，这消除了问题，但是我在Tez上遇到了重大的性能问题，因此我仍然希望有人在MR Engine上有能力解决。
我从未使用过Ambari，但是您可以尝试手工编辑mapred-site.xml并添加mapReduce.job.counters.max进入群集吗？
像您已经提到的另一个选择是Tez。
但是我很想知道
，但我在TEZ上遇到了重大的表现问题
由于在我的组织中，Tez在大多数用例中一直在击败地图。如果您可以分享您的问题(作为一个新问题(，我将尝试跟进。
此<property>在mapred-site.xml中设置为另一个类似的问题，
给您其他尝试的方法，但我不知道它是否有效
创建job-local.xml并设置<property>，使用 con.get(" mapReduce.job.counters.limit"(```您的项目''。或to con.set(" mapReduce.job.counters.limit"，" 200"(;
如果您在Mapred-site.xml中更改了设置，请检查其工作。
