Not able to start SPARK inside a container

Hello Team,
I just Installed docker 17.06.1-ce in centos 7.3, I am using spark-2.1.0-bin-hadoop2.7 inside the docker container, And trying to start the spark service by using the command ./
Getting below exception while starting the service.

[root@f451a7c9fcf8 sbin]# ./
