Chesnay Schepler reassigned FLINK-18175:
----------------------------------------
Assignee: Chesnay Schepler
> Add human readable summary for configured and derived memory sizes.
> -------------------------------------------------------------------
>
> Key: FLINK-18175
> URL: https://issues.apache.org/jira/browse/FLINK-18175
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Coordination
> Affects Versions: 1.10.1, 1.11.0
> Reporter: Xintong Song
> Assignee: Chesnay Schepler
> Priority: Major
>
> FLIP-49 & FLIP-116 introduces sophisticated memory configurations for
> TaskManager and Master processes. Before the JVM processes are started, Flink
> derives the accurate sizes for all necessary components, based on both
> explicit user configurations and implicit defaults.
> To make the configuration results (especially those implicitly derived) clear
> to users, it would be helpful to print them in the beginning of the process
> logs. Currently, we only have printed JVM parameters (TM & Master) dynamic
> memory configurations (TM only). They are incomplete (jvm overhead for both
> processes and off-heap memory for the master process are not presented) and
> unfriendly (in bytes).
> Therefore, I propose to add a human readable summary at the beginning of
> process logs.
