> Key: YARN-7124
> URL: https://issues.apache.org/jira/browse/YARN-7124
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodemanager
> Affects Versions: 2.9.0, 3.0.0-beta1
> Reporter: Daryn Sharp
> Assignee: Jason Lowe
> Priority: Critical
> Fix For: 2.9.0, 3.0.0, 3.1.0
>
> Attachments: YARN-7124.001.patch
>
>
> YARN-6288 changes the log aggregation writer to be an autoclosable.
> Unfortunately the try-with-resources block for the writer will either rename
> or delete the log while open.
> Assuming the NM's behavior is correct, deleting open files only results in
> ominous WARNs in the nodemanager log and increases the rate of logging in the
> NN when the implicit try-with-resource close fails. These red herrings
> complicate debugging efforts.
