I used to have `TASK_LOST` here, but my understanding is that `TASK_LOST` is used for abnormal situations, i.e. when the task is not finished not because of scheduler's direct command, but because of some external reasons. I agree, that a new task state is a very good solution. We have [this ticket](https://issues.apache.org/jira/browse/MESOS-343), one solution for which would be to introduce something like `TaskStatusExplained` or a protobuf message for every task. But maybe for this situation something like `TASK_ABANDONED` would be rather descriptive. - Alexander ----------------------------------------------------------- This is an automatically generated e-mail.
