当我搜索容器时，它显示如下：

yarn      38530 116969  0 Jul17 ?        00:00:00 bash /mnt/dfs/2/hadoop/yarn/local/usercache/sloth/appcache/application_1526888270443_0045/container_e12_1526888270443_0045_01_000039/default_container_executor.sh

我的回答是：

YarnTaskManager  pid = 38540   
 container        pid = 38533  
 ???              pid = 38530  
 nodemanager      pid = 116969

我转储yarntaskmanager的转储文件，大小为400m+。但是这个容器占用了更多的内存，我从日志中得知：

2018-07-18 10:16:27,875 INFO  monitor.ContainersMonitorImpl (ContainersMonitorImpl.java:run(464)) 
  - Memory usage of ProcessTree 38533 for container-id container_e12_1526888270443_0045_01_000039: 
 1.7 GB of 4 GB physical memory used; 4.1 GB of 8.4 GB virtual memory used

这个容器使用了1.7g内存，我查看了最近的日志，它上升的很慢。我不知道为什么使用的内存容器总是在上升，几天后它会上升到4gb，并且会被杀死，然后重新启动。我怎样才能阻止这一切的发生？谢谢你跟我上床！
