构造器详细资料

RegionServerFlushTableProcedureManager

public RegionServerFlushTableProcedureManager()

方法详细资料

start

public void start()

Start accepting flush table requests.

指定者:

start 在类中 RegionServerProcedureManager

stop

public void stop(boolean force)
          throws IOException

Close this and all running tasks

指定者:

stop 在类中 RegionServerProcedureManager

参数:

force - forcefully stop all running tasks

抛出:

IOException

buildSubprocedure

public Subprocedure buildSubprocedure(String table)

If in a running state, creates the specified subprocedure to flush table regions. Because this gets the local list of regions to flush and not the set the master had, there is a possibility of a race where regions may be missed.

参数:

table -

返回:

Subprocedure to submit to the ProcedureMemeber.

initialize

public void initialize(RegionServerServices rss)
                throws org.apache.zookeeper.KeeperException

Initialize this region server flush procedure manager Uses a zookeeper based member controller.

指定者:

initialize 在类中 RegionServerProcedureManager

参数:

rss - region server

抛出:

org.apache.zookeeper.KeeperException - if the zookeeper cannot be reached

getProcedureSignature

public String getProcedureSignature()

从类复制的说明: ProcedureManager

Return the unique signature of the procedure. This signature uniquely identifies the procedure. By default, this signature is the string used in the procedure controller (i.e., the root ZK node name for the procedure)

指定者:

getProcedureSignature 在类中 ProcedureManager
