--------------------------------
Summary: Track removed agents' operations in the Framework struct
Key: MESOS-9558
URL: https://issues.apache.org/jira/browse/MESOS-9558
Project: Mesos
Issue Type: Improvement
Components: master
Reporter: Greg Mann
The master currently relies on the agent ID in operation reconciliation
requests in order to send {{OPERATION_UNREACHABLE}} and
{{OPERATION_GONE_BY_OPERATOR}} updates. This also means that in the case of an
operation that was terminal-but-unacknowledged at the time of agent removal
(i.e. operation was FINISHED but the update not yet acknowledged), the
framework will receive OPERATION_UNREACHABLE/OPERATION_GONE_BY_OPERATOR for
reconciliation requests, when the master could report the actual terminal state
if it were retained.
We should consider updating the master to track unreachable/gone operations
explicitly in order to provide better reconciliation information in these cases.
