Xintong Song created FLINK-18175:
------------------------------------
Summary: 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
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.
