It should be enough to mock the receiving ends. > 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 > Assignee: zhangjing > > 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)
