             Summary: LocalizerRunner should give DIE action when all resources 
are localized
                 Key: YARN-3024
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 2.6.0
            Reporter: Chengbing Liu

We have observed that {{LocalizerRunner}} always gives a LIVE action at the end 
of localization process.

The problem is {{findNextResource()}} can return null even when {{pending}} was 
not empty prior to the call. This method removes localized resources from 
{{pending}}, therefore we should check the return value, and gives DIE action 
when it returns null.
