zhijiang updated FLINK-4354:
----------------------------
Description:
It is part of work for FLIP-6.
The {{HeartbeatManager}} is mainly used for monitoring heartbeat target and
reporting payloads.
For {{ResourceManager}} side, it would trigger monitoring the
{{HeartbeatTarget}} when receive registration from {{TaskManager}}, and
schedule a task to {{requestHeartbeat}} at interval time. If not receive
heartbeat response within duration time, the {{HeartbeatListener}} will notify
heartbeat timeout, then the {{ResourceManager}} should remove the internal
registered {{TaskManager}}.
For {{TaskManger}} side, it would trigger monitoring the {{HeartbeatTarget}}
when receive registration acknowledgement from {{ResourceManager}}. An it will
also be notified heartbeat timeout if not receive heartbeat request from
{{ResourceManager}} within duration time.
The current implementation will not interact payloads via heartbeat, and it can
be added if needed future.
was:
The {{ResourceManager}} initiates heartbeat messages via the {{RmLeaderID}}.
The {{TaskManager}} transmits its slot availability with each heartbeat. That
way, the RM will always know about available slots.
