> Some simple work on using HBase with Docker was committed into /dev-support as "hbase_docker;" all this did was stand up a standalone cluster from source and start a shell. Now seems like a good time to extend this to be useful for applications that could actual benefit the community, especially around testing. Some ideas:
> - Integration testing would be much more accessible if people could stand up distributed HBase clusters on a single host machine in a couple minutes and run our awesome hbase-it suite against it.
> - Binary compatibility testing of an HBase client is easiest when standing up an HBase cluster can be done once and then different client source/binary permutations run against it.
> - Upgrade testing, and especially rolling upgrade testing, doesn't have any upstream automation on build.apache.org, in part because it's a pain to set up x-node clusters on Apache infrastructure.
> This proposal, whether it stays under /dev-support or moves out into it's own top-level module ("hbase-docker" would conveniently fit the existing schema :-)), strives to create a simple framework for deploying "distributed," multi-container Apache HBase clusters.
