Docker is a complimentary solution to heavy weight VMs, as proposed in the vagrant portion of https://issues.apache.org/jira/browse/BIGTOP-1072.
The idea, i guess, would be to layer the
bigtop smokes on top of
hadoop distros from bigtop,
on top of the OS.
This layering would ideally be modular so that different bigtop related tasks could run in docker LXCE isolation.
