> 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.
