Subject [jira] [Created] (YARN-5177) Make Node-Manager Download-Resource Component extensible.
Date Sat, 28 May 2016 00:35:12 GMT
Emeka created YARN-5177:

             Summary: 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
            Priority: Minor

- 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.

- 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.
