------------------------------------
Summary: Default slot resource is calculated inconsistently for
pending / registered TMs
Key: FLINK-21433
URL: https://issues.apache.org/jira/browse/FLINK-21433
Project: Flink
Issue Type: Sub-task
Components: Runtime / Coordination
Reporter: Xintong Song
Assignee: Xintong Song
For a {{PendingTaskManager}}, the default slot resource is decided by
{{ResourceAllocationStrategy}}. However, this default slot resource is ignored
in {{FineGrainedSlotManager#allocateResource}}.
On the TM side, the default slot profile is calculated via
{{TaskExecutorResourceUtils#generateDefaultSlotResourceProfile}}. This may lead
to registered TM does not match the pending TM.
