@VisibleForTesting

boolean asynchronous)

示例2: forceOfflineInZK
import org.apache.hadoop.hbase.client.HBaseAdmin; //導入方法依賴的package包/類
/**
* In 0.90, this forces an HRI offline by setting the RegionTransitionData
* in ZK to have HBCK_CODE_NAME as the server. This is a special case in
* the AssignmentManager that attempts an assign call by the master.
*
* @see org.apache.hadoop.hbase.master.AssignementManager#handleHBCK
*
* This doesn't seem to work properly in the updated version of 0.92+'s hbck
* so we use assign to force the region into transition. This has the
* side-effect of requiring a HRegionInfo that considers regionId (timestamp)
* in comparators that is addressed by HBASE-5563.
