Vinod Kone updated MESOS-5262: ------------------------------ Target Version/s: (was: 1.1.0) > 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 > Labels: mesosphere > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
