> Configuration.loadResource should skip empty resources
> ------------------------------------------------------
>
> Key: HADOOP-9453
> URL: https://issues.apache.org/jira/browse/HADOOP-9453
> Project: Hadoop Common
> Issue Type: Improvement
> Components: conf
> Affects Versions: 3.0.0
> Reporter: Steve Loughran
> Priority: Minor
>
> YARN-535 shows that having a 0-byte {yarn-site}} file (created due to the
> test itself) breaks configuration loads, as it is a default resource that no
> longer parses.
> The resource loader code skips missing files -it should do the same for
> 0-byte files.
