I also expect management tools & their hadoop installations to restore the 2.6 value. Changing the ratio is the solution that would be viable in production with vmem checks enabled > [Java 8] Over usage of virtual memory > ------------------------------------- > > Key: YARN-4714 > URL: https://issues.apache.org/jira/browse/YARN-4714 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Mohammad Kamrul Islam > Assignee: Mohammad Kamrul Islam > Priority: Blocker > Attachments: HADOOP-11364.01.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
