------------------------------------------------------------
Not sure if it's a right behavior to remove startAll() in
DataNode#runDatanodeDaemon.
The method BlockPoolManager#startAll is invoked in different places, see
attached screenshot. The BlockPoolManager#startAll invoked in runDatanodeDaemon
seems used for the test.
