Tsuyoshi OZAWA commented on YARN-3086:

I'm was not able to run any the tests because the tests in "trunk" don't seem 
to pass

The intermittent test failure can be observed currently for some reasons - port 
conflict, shortage of resource, and timing issues. We should fix them, but the 
problems are still there. I recommend you to run test under the related 
directory - in this case, I recommend you to run tests under 
 instead of root directory.

Am I supposed to develop against a version specific branch?

The develop branch is trunk, so I recommend you to develop on trunk except the 
problem is branch-specific problem.

>                 URL: https://issues.apache.org/jira/browse/YARN-3086
>             Project: Hadoop YARN
>          Issue Type: Improvement
>          Components: test
>            Reporter: Robert Metzger
>            Priority: Minor
>         Attachments: YARN-3086.patch
> 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.
