--------------------------------------------
> I'd suggest the thread name be even shorter. ...
I agree. Ideally, we only need
{code}
BP-948066398-XXXX-1490219911913 heartbeat to localhost/127.0.0.1:53014
{code}
However, the BP id may be missing in the beginning. How about using the NS id
if BP id is missing? The NS id is available in
BlockPoolManager.doRefreshNamenodes(..) but it is not passed down the road.
> BPServiceActor thread name is too long
