I get stuck when i launch HortonWorks Inside VirtualBox. the host is a CentOS 7 system. I installed the 5.1.6 virtualbox version. execution stop and block at the point: Starting SandboxContainer.
I have tried VM Ware as well but it is also showing the same behavior.
I am running Windows8 with 8Gb of RAM. For the VM i reduced the allocated 8Gb RAM to 6Gb as wel
The base memory requirement for sandbox 2.5 is 8 GB ! but all the same at least it should fire up but perform badly. Can you attach a screenshot.
What is the sandbox setup like ? You will net to tweak the network check the attached screenshot from my 2.5 Sandbox
Hope that helps
