Akira AJISAKA commented on YARN-4714:
-------------------------------------
In YARN-2225, Tsuyoshi commented:
bq. IMHO, I prefer to make the default value of the vmem ratio larger. How
about closing this issue and doing it on another jira(or, moving HADOOP-11364
to YARN issue) since the addressing problem is different from this issue?
so I moved this issue to YARN. Let's make the default value of vmem ratio
larger in this issue.

> In our Hadoop 2 + Java8 effort , we found few jobs are being Killed by Hadoop
> due to excessive virtual memory allocation. Although the physical memory
> usage is low.
> The most common error message is "Container [pid=??,containerID=container_??]
> is running beyond virtual memory limits. Current usage: 365.1 MB of 1 GB
> physical memory used; 3.2 GB of 2.1 GB virtual memory used. Killing
> container."
> We see this problem for MR job as well as in spark driver/executor.
