Hi Guangya, Hmm!...That is strange in my case!
If I run from the mesos-execute on one of the slave/master node then the tasks get their resources and they get scheduled well. But if I start the mesos-execute on another node which is neither slave/master then I have this issue. I am using an lxc container on master as a client to launch the tasks. This is also in the same network as master/slaves. And I just launch the task as you did. But the tasks are not getting scheduled. On master the logs are same as I sent you before Deactivating framework 77539063-89ce-4efa-a20b-ca788abbd912-0066 On both of the slaves I can see the below logs I1005 13:23:32.547987 4831 slave.cpp:1980] Asked to shut down framework 77539063-89ce-4efa-a20b-ca788abbd912-0060 by [email protected]:5050 W1005 13:23:32.548135 4831 slave.cpp:1995] Cannot shut down unknown framework 77539063-89ce-4efa-a20b-ca788abbd912-0060 I1005 13:23:33.697707 4833 slave.cpp:3926] Current disk usage 3.60%.
