A few questions, I noticed that trying to mount /hadoop to a host mount point is not working. In the dockerfile that is building the core hortonworks/sandbox-hdp:3.0.1 exposing the volume /hadoop? Is there a volume mapping in the dockerfile? Is the dockerfile for this specific version published? I have looked that the git and it is rather old. Lastly versions of the Sandbox are behind current releases, what is the plan to keep sandbox in sync with releases?
Some commentary, I am not a fan of non-exposed data volumes so I assume this is something I have overlooked possibly but moving the core docker repository from /var/lib, etc is not a clean option and documenting volumes that can be exposed for storage of data would be ideal. I will await responses to the above, thanks in advance
