-------------------------------------
Summary: Introduce a heartbeat mechanism for executor <-> agent
communication.
Key: MESOS-7564
URL: https://issues.apache.org/jira/browse/MESOS-7564
Project: Mesos
Issue Type: Task
Reporter: Anand Mazumdar
Currently, we do not have heartbeats for executor <-> agent communication. This
is especially problematic in scenarios when IPFilters are enabled since the
default conntrack keep alive timeout is 5 days. When that timeout elapses, the
executor doesn't get notified via a socket disconnection when the agent process
restarts. The executor would then get killed if it doesn't re-register when the
agent recovery process is completed.
Enabling application level heartbeats or TCP KeepAlive's can be a possible way
for fixing this issue.
