我正在使用hadoop2.7.3在emr上运行mapreduce/hadoop。在aws上安装，jar是用maven shade插件构建的。它在等待资源管理器时被无限地卡住了，但我在日志文件或在线上完全找不到任何东西。
在 job.waitForCompletion ，它包括以下几行：

020-01-25 05:52:41,346 INFO org.apache.hadoop.yarn.client.api.impl.TimelineClientImpl (main): Timeline service address: http://ip-172-31-13-41.us-west-2.compute.internal:8188/ws/v1/timeline/
2020-01-25 05:52:41,356 INFO org.apache.hadoop.yarn.client.RMProxy (main): Connecting to ResourceManager at ip-172-31-13-41.us-west-2.compute.internal/172.31.13.41:8032

然后它就坐在那里。。。从不取得进展，必须关闭集群或手动终止任务。
有趣的是 hadoop jar <arguments> ，我可以在本地重现这一步，但我不知道是什么原因造成的。
大约25分钟后，它在打开jar时失败：

After 25 minutes or so, the job produces output of the form:

Failing this attempt

这在aws emr和本地都会发生。从未见过这种错误，使用电子病历直接开箱即用。
你知道为什么会这样吗？坏jar？可能与另一个未回答的问题有关
