The thing is for mesos versions <= 1.2, with strict registry disabled the agents were allowed to re-register with the master after having being removed due to consecutive healthcheck failures and as a result the frameworks could still receive TASK_RUNNING after TASK_LOST (due to agent removed). So, we are really changing the semantics of TASK_LOST. - Megha ----------------------------------------------------------- This is an automatically generated e-mail.
