Tsuyoshi OZAWA commented on YARN-3086:

The following is a suggestion from [~rmetzger] in yarn-dev mailing list:
If you want to maintain the current value of 4GB as the default value, I
probably need to introduce a new configuration value, similar to:

    YARN_PREFIX + "minicluster.control-resource-monitoring";

Or is there another approach you would prefer?

I'll add a patch to the JIRA once I've found time to fix it.

> Make NodeManager memory configurable in MiniYARNCluster

>                 Key: YARN-3086
>                 URL: https://issues.apache.org/jira/browse/YARN-3086
>             Project: Hadoop YARN
>          Issue Type: Improvement
>          Components: test
>            Reporter: Robert Metzger
>            Priority: Minor
> Apache Flink has a build-in YARN client to deploy it to YARN clusters.
> Recently, we added more tests for the client, using the MiniYARNCluster.
> One of the tests is requesting more containers than available. This test 
> works well on machines with enough memory, but on travis-ci (our test 
> environment), the available main memory is limited to 3 GB. 
> Therefore, I want to set custom amount of memory for each NodeManager.
> Right now, the NodeManager memory is hardcoded to 4GB.
> As discussed on the yarn-dev list, I'm going to create a patch for this issue.
