Kurt Young created FLINK-4348: --------------------------------- Summary: implement communication from ResourceManager to TaskManager Key: FLINK-4348 URL: https://issues.apache.org/jira/browse/FLINK-4348 Project: Flink Issue Type: Sub-task Components: Cluster Management Reporter: Kurt Young
There are mainly 3 logics initiated from RM to TM: * Heartbeat, RM use heartbeat to sync with TM's slot status * SlotRequest, when RM decides to assign slot to JM, should first try to send request to TM for slot. TM can either accept or reject this request. * FailureNotify, in some corner cases, TM will be marked as invalid by cluster manager master(e.g. yarn master), but TM itself does not realize. RM should send failure notify to TM and TM can terminate itself -- This message was sent by Atlassian JIRA (v6.3.4#6332)
