--------------------------------
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}}
