      Description

      Setting up and tearing down HBaseTestingUtility instances in unit tests is very expensive. On my MacBook it takes about 10 seconds to set up a MiniCluster, and 7 seconds to tear it down. When multiplied by the number of test classes that use this facility, that's a lot of time in the build.

      This factory assumes that the JVM is being re-used across test classes in the build, otherwise this pattern won't work.

      I don't think this is appropriate for every use, but I think it can be applicable in a great many cases - especially where developers just want a simple MiniCluster with 1 slave.
