             Summary: Disable enforcing of YARN container virtual memory limits in tests
                 Key: FLINK-10951
                 URL: https://issues.apache.org/jira/browse/FLINK-10951
             Project: Flink
          Issue Type: Bug
            Reporter: Gary Yao


*Description*
The Jepsen YARN tests sporadically fail because TM containers are exceeding their virtual memory limits:

{noformat}
Closing TaskExecutor connection container_1541436244107_0001_01_000005 because: Container [pid=32403,containerID=container_1541436244107_0001_01_000005] is running beyond virtual memory limits. Current usage: 970.2 MB of 2 GB physical memory used; 4.2 GB of 4.2 GB virtual memory used. Killing container.
{noformat}

By default YARN enforces a virtual memory limit of 2.1 times the requested physical memory. However, in my experiments, the virtual memory of a JVM process running the {{ClusterEntryPoint}} (without submitting job) is already in the region of 3.3 GB. Hence, the virtual memory enforcement should be disabled.

*Acceptance Criteria*
* {{yarn.nodemanager.vmem-check-enabled}} is {{false}} in {{yarn-site.xml}}
