GJL opened a new pull request #7149: [FLINK-10951][tests] Set
yarn.nodemanager.vmem-check-enabled to false
URL: https://github.com/apache/flink/pull/7149
## What is the purpose of the change
*The Jepsen YARN tests sporadically fail because TM containers are exceeding
their virtual memory limits. This PR disables the virtual memory check.*
## Brief change log
- *Set yarn.nodemanager.vmem-check-enabled to false*
- *Re-order config keys alphabetically*
## Verifying this change
This change is already covered by existing tests, such as *Jepsen test
suite*.

- Dependencies (does it add or upgrade a dependency): (yes / **no**)
- The public API, i.e., is any changed class annotated with
`@Public(Evolving)`: (yes / **no**)
- The serializers: (yes / **no** / don't know)
- The runtime per-record code paths (performance sensitive): (yes / **no**
/ don't know)
- Anything that affects deployment or recovery: JobManager (and its
components), Checkpointing, Yarn/Mesos, ZooKeeper: (yes / **no** / don't know)
- The S3 file system connector: (yes / **no** / don't know)

> 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: Improvement
> Components: Tests
> Affects Versions: 1.8.0
> Reporter: Gary Yao
> Assignee: Gary Yao
> Priority: Critical
> Labels: pull-request-available
> Fix For: 1.8.0
>
>
> *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}}
