> Key: FLINK-21047
> URL: https://issues.apache.org/jira/browse/FLINK-21047
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Coordination, Runtime / Metrics
> Affects Versions: 1.11.3, 1.12.1
> Reporter: Yangze Guo
> Priority: Major
>
> In FLINK-16640, we extend ResourceOverview and TaskManager(Details)Info for registered/free resources. However, the implementation is based on the assumption that all the registered task executors are homogeneous with the default resource spec. This assumption will be broken in standalone mode when user manually starts heterogeneous task executors.
> We need to calculate the registered/free resources according to the exact {{defaultSlotResourceProfile}} and {{totalResourceProfile}} of \{{TaskExecutorRegistration}}s.
