类 ClosedRegionHandler

java.lang.Object

org.apache.hadoop.hbase.executor.EventHandler

org.apache.hadoop.hbase.master.handler.ClosedRegionHandler

所有已实现的接口:

Comparable<Runnable>, Runnable, TotesHRegionInfo

@InterfaceAudience.Private
public class ClosedRegionHandler
extends EventHandler
implements TotesHRegionInfo

Handles CLOSED region event on Master.

If table is being disabled, deletes ZK unassigned node and removes from regions in transition.

Otherwise, assigns the region to another server.

ClosedRegionHandler

public ClosedRegionHandler(Server server,
                   AssignmentManager assignmentManager,
                   HRegionInfo regionInfo)

方法详细资料

getPriority

public int getPriority()

从类复制的说明: EventHandler

Get the priority level for this handler instance. This uses natural ordering so lower numbers are higher priority.

Lowest priority is Integer.MAX_VALUE. Highest priority is 0.

Subclasses should override this method to allow prioritizing handlers.

Handlers with the same priority are handled in FIFO order.

覆盖:

getPriority 在类中 EventHandler

返回:

Integer.MAX_VALUE by default, override to set higher priorities

getHRegionInfo

public HRegionInfo getHRegionInfo()

指定者:

getHRegionInfo 在接口中 TotesHRegionInfo

返回:

HRegionInfo instance.

toString

public String toString()

覆盖:

toString 在类中 EventHandler

process

public void process()

从类复制的说明: EventHandler

This method is the main processing loop to be implemented by the various subclasses.

指定者:

process 在类中 EventHandler
