I have a question on the Executors. I see that a framework can use 1 or more executors on a slave. At finest granularity, one could launch each task in a separate executor (our tasks are relatively long lived). This at least seems like a good choice since resource isolation of executors now happens for each task. And, I could eliminate the work in my executor of forking processes to execute tasks.
When a task completes (either normally or by getting a kill request), I would like the executor to exit as well. Playing with this, I have the status of TASK_COMPLETED being sent via the driver, followed by a wait of about 5 secs (not sure I need this for any mesos communication to happen for status), and then, say, a System.exit(). However, this is producing a TASK_LOST to my framework scheduler. Shouldn't the previous sending of TASK_COMPLETED status prevent the TASK_LOST update? I am using Mesos 0.16. Sharma
