Java EMR上的MapReduce未联系RMProxy并在等待resourcemanager时卡住？

我正在使用hadoop 2.7.3在EMR上运行mapreduce/hadoop。在AWS上安装，jar是用maven shade插件构建的。它会无限期地等待ResourceManager，但我在日志文件或在线上完全找不到任何东西

在

job.waitForCompletion

中，出现以下行：

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。。。从未取得进展，必须关闭群集或手动终止任务

有趣的是，在尝试了数百个实验之后，通过运行hadoop jar，似乎有问题的一行是

job.setJar（）

为什么，我不知道。它在intellij下工作正常，但在本地和intellij下使用

hadoop

命令都会可靠地崩溃。

exit-1000——这不是常见错误。

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


AM Container for appattempt_1580058321574_0005_000001 exited with exitCode: -1000
