Qian Zhang updated MESOS-5225:
------------------------------
Description:
Reproduce steps:
1. Start master
{code}
sudo ./bin/mesos-master.sh --work_dir=/tmp
{code}
2. Start agent
{code}
sudo ./bin/mesos-slave.sh --master=192.168.122.171:5050 --containerizers=mesos
--image_providers=docker
--isolation=filesystem/linux,docker/runtime,network/cni
--network_cni_config_dir=/opt/cni/net_configs
--network_cni_plugins_dir=/opt/cni/plugins
{code}
3. Launch a command task with mesos-execute, and it will join a CNI network
{{net1}}.
{code}
sudo src/mesos-execute --master=192.168.122.171:5050 --name=test
--docker_image=library/busybox --networks=net1 --command="sleep 10" --shell=true
I0418 08:25:35.746758 24923 scheduler.cpp:177] Version: 0.29.0
Subscribed with ID '3c4796f0-eee7-4939-a036-7c6387c370eb-0000'
Submitted task 'test' to agent 'b74535d8-276f-4e09-ab47-53e3721ab271-S0'
Received status update TASK_FAILED for task 'test'
message: 'Executor terminated'
source: SOURCE_AGENT
reason: REASON_EXECUTOR_TERMINATED
{code}
So the task failed with the reason "executor terminated". Here is the agent log:

So the reason why executor terminated is, the libprocess in it failed to
