We may be debating semantics of uninstall here but "stop" does not uninstall. Mostly because one can "start" and then get back the same configured state. Of course, the notion of still having a disk foot print after stop is no longer valid in the YARN world.
I would say that "destroy" is the equivalent of uninstall. I am mostly modeling the life-cycle against a traditional deployment of HBase. Basically, you install, configure, start, stop, and then uninstall. The original question stemmed from the fact that uninstall of HBase will not delete the HDFS folder.
