Yitong Zhou commented on HADOOP-11364:
--------------------------------------
Is yarn.nodemanager.vmem-pmem-ratio and yarn.nodemanager.vmem-check-enabled are
only supposed to be effective when set in yarn-site.xml or before a container
is launched? I tried to set it via JobConf, and did not see an effect.
Mohammad's suggestion tweaking jvm.opts worked though.
> [Java 8] Over usage of virtual memory

> Key: HADOOP-11364
> URL: https://issues.apache.org/jira/browse/HADOOP-11364
> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Mohammad Kamrul Islam
> Assignee: Mohammad Kamrul Islam
>
> 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.
