What changed is that the `Action` interface and `run` method was extracted into a separate `ClientPool` interface (That's why we had to do the renaming). This interface is implemented by the `CacheClientPool` and `ClientPoolImpl` classes (and indirectly by `HiveClientPool`). When someone calls `run` on an instance of `CachedClientPool`, we just fetch the appropriate `HiveClientPool` instance from the cache and call `run` on that instance. -- This is an automated message from the Apache Git Service.
