> Recover localized resource cache state upon nodemanager restart

> Key: YARN-1338
> URL: https://issues.apache.org/jira/browse/YARN-1338
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: nodemanager
> Affects Versions: 2.3.0
> Reporter: Jason Lowe
> Assignee: Jason Lowe
> Attachments: YARN-1338.patch, YARN-1338v2.patch,

>
>
> Today when node manager restarts we clean up all the distributed cache files
> from disk. This is definitely not ideal from 2 aspects.
> * For work preserving restart we definitely want them as running containers
> are using them
> * For even non work preserving restart this will be useful in the sense that
> we don't have to download them again if needed by future tasks.
