> Key: YARN-8328
> URL: https://issues.apache.org/jira/browse/YARN-8328
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Jonathan Eagles
> Priority: Major

>
> This happens frequently in the MiniYarnCluster setup where a job completes
> and then the cluster is shutdown. Often the jobs are scheduled to delay
> deletion of the log files so that container logs are available for debugging.
> A scheduled log deletion has a default value of 3 hours. When the
> NonAggregating LogHandler is stopped it waits 10 seconds for all delayed
> scheduled log deletions to occur and then shuts down.
> A test developer has to make a trade of to either 1) set the log deletion to
> 0 to have the tests quickly shutdown but get no container logs to debug or 2)
> keep the log deletion at 3 hours and incur the 10 second timeout for each
> test suit.
