---------------------------------------
There is a PR for this JIRA now: https://github.com/apache/flink/pull/2615
> Simplify access to MetricStore
> ------------------------------
>
> Key: FLINK-4775
> URL: https://issues.apache.org/jira/browse/FLINK-4775
> Project: Flink
> Issue Type: Improvement
> Components: Metrics, Webfrontend
> Affects Versions: 1.1.2
> Reporter: Chesnay Schepler
> Assignee: Chesnay Schepler
> Fix For: 1.2.0
>
>
> A few utility methods can be added to the MetricStore, which would make
> working with it a lot easier.
> This includes getXMetricStore(args) methods that, for example, return the
> appropriate TaskMetricStore, without requiring the accessor to traverse the
> structure(and do several null checks) themselves.
> In addition, a getMetric(name, defaultValue) method would ease the issue of
> metrics not being updated yet.
