> Key: FLINK-10252
> URL: https://issues.apache.org/jira/browse/FLINK-10252
> Project: Flink
> Issue Type: Sub-task
> Components: Metrics
> Affects Versions: 1.5.3, 1.6.0, 1.7.0
> Reporter: Till Rohrmann
> Assignee: vinoyang
> Priority: Critical
> Labels: pull-request-available
> Fix For: 1.5.6, 1.6.3, 1.7.0
>
>
> Since the {{MetricQueryService}} is implemented as an Akka actor, it can only
> send messages of a smaller size then the current {{akka.framesize}}. We
> should check similarly to FLINK-10251 whether the payload exceeds the maximum
> framesize and fail fast if it is true.
