      Description

      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.
