> My testing suggests that we could shave about a minute off the entire suite 
> if we only had to start up a single DFS instance instead of a new one for 
> each test. Stack has investigated using ant to perform this initialization 
> task, but come up empty handed.
> I propose that we should expect the developer running the test suite to start 
> a DFS before running "ant test". We could provide a bin/hbase command that 
> does specifically that in order to make it easy. This would save not only the 
> initial start up time but all the startup time of all tests and test suite 
> runs you execute in a session of development and testing. 
> Do people think that an extra step to testing would be too hard for new (or 
> lazy existing) developers?
