> Key: YARN-535
> URL: https://issues.apache.org/jira/browse/YARN-535
> Project: Hadoop YARN
> Issue Type: Bug
> Components: applications
> Affects Versions: 3.0.0
> Environment: OS/X laptop, HFS+ filesystem
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Minor
> Attachments: YARN-535-02.patch, YARN-535.patch
>
>
> the setup phase of {{TestUnmanagedAMLauncher}} overwrites {{yarn-site.xml}}.
> As {{Configuration.writeXml()}} does a reread of all resources, this will
> break if the (open-for-writing) resource is already visible as an empty file.
> This leaves a corrupted {{target/test-classes/yarn-site.xml}}, which breaks
> later test runs -because it is not overwritten by later incremental builds,
> due to timestamps.
