public class GCRegionProcedure
extends AbstractStateMachineRegionProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.GCRegionState>

GC a Region that is no longer in use. It has been split or merged away. Caller determines if it is GC time. This Procedure does not check.

This is a Region StateMachine Procedure. We take a read lock on the Table and then exclusive on the Region.

getTableOperationType

public TableProcedureInterface.TableOperationType getTableOperationType()

从接口复制的说明: TableProcedureInterface

Given an operation type we can take decisions about what to do with pending operations. e.g. if we get a delete and we have some table operation pending (e.g. add column) we can abort those operations.

指定者:

getTableOperationType 在接口中 TableProcedureInterface

指定者:

getTableOperationType 在类中 AbstractStateMachineRegionProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.GCRegionState>

返回:

the operation type that the procedure is executing.
