类 HRegionLocation

java.lang.Object

org.apache.hadoop.hbase.HRegionLocation

所有已实现的接口:

Comparable<HRegionLocation>

@InterfaceAudience.Public
public class HRegionLocation
extends Object
implements Comparable<HRegionLocation>

Data structure to hold RegionInfo and the address for the hosting HRegionServer. Immutable. Comparable, but we compare the 'location' only: i.e. the hostname and port, and *not* the regioninfo. This means two instances are the same if they refer to the same 'location' (the same hostname and port), though they may be carrying different regions. On a big cluster, each client will have thousands of instances of this object, often 100 000 of them if not million. It's important to keep the object size as small as possible.
This interface has been marked InterfaceAudience.Public in 0.96 and 0.98.
