----------------------------------------------
When you come around to doing this, please write a test-case first to reproduce
this. Tx.
> Failed resource localization might introduce a race condition.

> Key: YARN-544
> URL: https://issues.apache.org/jira/browse/YARN-544
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Omkar Vinit Joshi
> Assignee: Omkar Vinit Joshi
>
> When resource localization fails [Public localizer /
> LocalizerRunner(Private)] it sends ContainerResourceFailedEvent to the
> containers which then sends ResourceReleaseEvent to the failed resource. In
> the end when LocalizedResource's ref count drops to 0 its state is changed
> from DOWNLOADING to INIT.
> Now if a Resource gets ResourceRequestEvent in between
> ContainerResourceFailedEvent and last ResourceReleaseEvent then for that
> resource ref count will not drop to 0 and the container which sent the
> ResourceRequestEvent will keep waiting.
