Benjamin Mahler created MESOS-8476:
--------------------------------------
Summary: Store executor container status in the agent after it
launches.
Key: MESOS-8476
URL: https://issues.apache.org/jira/browse/MESOS-8476
Project: Mesos
Issue Type: Improvement
Components: agent, containerization
Environment: Currently, the agent will retrieve the container status
upon on each task status update in order to augment the status update with the
container status information (e.g. ip address). This has made the status update
processing asynchronous when it comes to the side effects to the agent data
structures. Consequently, several bugs have occurred: MESOS-5380, MESOS-7865,
MESOS-8459.
It's odd that the container status, which seems to define the properties of the
executor's container, needs to be retrieved in the status update path. Rather,
the agent could just store this once when the executor is launched and remember
it.
Currently, the containerizer interface exposes the container status only as a
separate call. However, to simplify the fix here, the containerizer could
expose it directly in the {{launch()}} Future.
