类 CloseRegionHandler

java.lang.Object

org.apache.hadoop.hbase.executor.EventHandler

org.apache.hadoop.hbase.regionserver.handler.CloseRegionHandler

所有已实现的接口:

Comparable<Runnable>, Runnable

直接已知子类:

CloseMetaHandler

@InterfaceAudience.Private
public class CloseRegionHandler
extends EventHandler

Handles closing of a region on a region server.

Now for regular close region request, we will use UnassignRegionHandler instead. But when shutting down the region server, will also close regions and the related methods still use this class so we keep it here.
