Interface ContainerResolver

public interface ContainerResolver

Interface for implementations which knows how to resolve container locations. This is meant for similar concepts found from a map/reduce framework to execute containers as close for the input as possible. For example if task main purpose is to access HDFS resources it will be much faster if those containers can be executed on a same host where HDFS file/block is physically placed.
