Subject [jira] [Created] (MESOS-5262) slave::statusUpdate() should always ACK the status update sent by executor

---------------------------------

             Summary: slave::statusUpdate() should always ACK the status update sent by executor
                 Key: MESOS-5262
                 URL: https://issues.apache.org/jira/browse/MESOS-5262
             Project: Mesos
          Issue Type: Improvement
          Components: slave
            Reporter: Qian Zhang


In {{slave::statusUpdate()}}, there are several scenarios where agent ignores a status update
sent by the executor and will not send an ACK to the executor, e.g.:

When agent receives a {{ShutdownFrameworkMessage}} from master, {{slave::shutdownFramework()}}
will be called. In this method, we will set the state of framework to {{TERMINATING}} and
send a {{ShutdownExecutorMessage}} to executor. When executor receives that message, usually
it will kill the tasks and send {{TASK_KILLED}} status update to agent. Agent will receive
that message and handle it in {{slave::statusUpdate()}}, but according to the currently logic
of {{slave::statusUpdate()}}, it will ignore the status update if the state of framework is
{{TERMINATING}}, so agent will not send an ACK to the executor.

Since executor may rely on the ACK (e.g., HTTP command executor relies on the ACK of a terminal
status update to terminate itself), we should enhance it such that executor can always get
an ACK for the status update sent by it.
