Class RegisterStreamer

java.lang.Object

alluxio.worker.block.RegisterStreamer

All Implemented Interfaces:

Iterator<RegisterWorkerPRequest>

public class RegisterStreamer
extends Object
implements Iterator<RegisterWorkerPRequest>

This class oversees the logic of registering with the master using a stream of RegisterWorkerPRequest. The stream lifecycle management lives internal to this instance.
