Description
There is something called BlockManagerMaster that doesn't run on the driver (only on the Executors). There is a thing called BlockManagerWorker that is not really a "worker" component but a bridge between the connection manager and the block manager. I found these names confusing on my first read of this code and in the last week two other people have asked me to explain it to them. So perhaps we can find more intuitive names here...
