Good day,
How to run several task simultaneously using Chronos on one mesos slave?
I try to run second task when first task is still running, but Chronos doesn't start second task and mark it as "failure". In the log I see following messages:
Oct 01, 2014 11:44:44 AM com.airbnb.scheduler.state.MesosStatePersistenceStore com$airbnb$scheduler$state$MesosStatePersistenceStore$$remove INFO: Purging entry 'T_ct:1412178282735:0:2' via: org.apache.mesos.state.ZooKeeperState Oct 01, 2014 11:44:44 AM com.airbnb.scheduler.mesos.MesosJobFramework processTask INFO: Task 'ct:1412178282735:0:2' launched, status: 'DRIVER_RUNNING' Oct 01, 2014 11:44:44 AM com.airbnb.scheduler.mesos.MesosJobFramework getNextTask$1 INFO: No tasks scheduled!

Adding to state
As you see, second task is lost and failed. There is no such problem with using Marathon, it can run a lot of tasks simultaneously on Mesos. Do you know what can be reason of such behaviour?
Thank you, in advance.
P.S.: Our team find your project very useful for us, thank you for this work.
