Hello! Today I began working on a more advanced version of mesos-submit
that will handle hot-spares.
I was assuming that TASK_{FAILED,FINISHED,LOST,KILLED} were the status
updates that meant that I needed to start a new spare process, as the
monitored task was killed. However, I noticed that I often recieved
TASK_LOSTs, and every 5 seconds, my scheduler would think its tasks had all
died, so it'd restart too many. Nevertheless, the tasks would reappear
later on, and I could see them in the web interface of Mesos, continuing to
run.
What is going on?
Thanks!
David
