> As part of Datanode startup, {{BlockPoolManager#startAll}} which starts all {{BPServiceActor}}
threads is called twice.
> First in {{Datanode}} constructor, {{Datanode#startDataNode}} is called which does {{BlockPoolManager#refreshNamenodes}}
inside which we do {{startAll}}
> And as part of {{Datanode#runDatanodeDaemon}} we again call {{BlockPoolManager#startAll}}.
> Since {{BPServiceActor}} checks if {{bpThread}} is already running, before starting them
again, the second call is ignored.
