I have added some libraries and updated some software on the HDP Sandbox container, so clients can test new functionality of our product without getting their infrastructure teams involved. That works fine, but what I'm encountering now, is once the containers with the changes made have come up, the VM hosting the container is inaccessible. I can ssh from my terminal to the container, but can no longer access the terminal of the VM via virtualbox or the web shell that was accessible prior to committing changes to the docker container.
What do you mean by 'unable to access the VM'? From what I read on your initial post ( adding in extra functionality ) I'm guessing you might be maxing out the memory of the machine which would explain the weird functionality.
