> Make Node-Manager Download-Resource Component extensible.
> ---------------------------------------------------------
>
> Key: YARN-5177
> URL: https://issues.apache.org/jira/browse/YARN-5177
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: nodemanager
> Affects Versions: 2.7.0
> Reporter: Emeka
> Assignee: Emeka
> Priority: Minor
> Labels: oct16-medium
> Attachments: YARN-5177-V0.patch
>
>
> Problem:
> - Downloading files to a local machine/node is called "resource-localization".
> - There are two components that perform resource-location (PublicLocalizer
> and ComponetLocalizers)
> - Both components utilizes FSDownload.class to perform their downloads.
> - We need a custom implementation of FSDownload.
> Solution:
> - With this change, we make FSDownload.class extensible by wrapping it in a
> new ResourceDownloader.interface
> - We also update the PublicLocalizer and ComponetLocalizers to load
> ResourceDownloader rather than FSDownload.
> - NOTE: We use reflection to load the right implementation during runtime.
