> Project: Hadoop YARN

> Components: api
> Affects Versions: 3.0.0
> Reporter: Jason Darrell Lowe
> Priority: Major
> Attachments: YARN-7576.001.patch
>
>
> Precommit builds are complaining about a findbugs warning:
> {noformat}
> EI org.apache.hadoop.yarn.api.records.Resource.getResources() may expose
> internal representation by returning Resource.resources
>
> Bug type EI_EXPOSE_REP (click for details)
> In class org.apache.hadoop.yarn.api.records.Resource
> In method org.apache.hadoop.yarn.api.records.Resource.getResources()
> Field org.apache.hadoop.yarn.api.records.Resource.resources
> At Resource.java:[line 213]
> Returning a reference to a mutable object value stored in one of the object's
> fields exposes the internal representation of the object. If instances are
> accessed by untrusted code, and unchecked changes to the mutable object would
> compromise security or other important properties, you will need to do
> something different. Returning a new copy of the object is better approach in
> many situations.
