Creating redis failed due to error " uses less CPUs (None) than the minimum required (0.01). Please update your executor,"

[zousheng]

Hi,

II am trying to create single redis instance in mr-redis UI (all of mr-redis env is set up in centos 7.2 ), and it failed. I checked the executor and mesos master logs, the scheduler logs indicates the Executor lost on slave, I am a little confused about this, and the mesos-master log "uses less CPUs (None) than the minimum required (0.01)".

I have checked the environment, docker and go env, everyting works fine. Would you please give some advice? thanks

the master logs shows that:
