> IOMetrics transfer through ExecGraph does not work for failed jobs
> ------------------------------------------------------------------
>
> Key: FLINK-5645
> URL: https://issues.apache.org/jira/browse/FLINK-5645
> Project: Flink
> Issue Type: Bug
> Components: Metrics, Webfrontend
> Affects Versions: 1.2.0, 1.3.0
> Reporter: Chesnay Schepler
> Assignee: Chesnay Schepler
> Priority: Blocker
>
> While a job is running the web-interface polls IO metrics using the
> MetricFetcher/MetricQueryService. For finished jobs these metrics are stored
> in the ExecutionGraph; each vertex has an IOMetrics object; basically a
> snapshot taken when the task was finished.
> For completed jobs this mechanism is working. However, for failed jobs it
> doesn't; in this case last fetched metrics are displayed.
> This isn't intended behavior and should be fixed.
