All Implemented Interfaces:

Comparable<Procedure<MasterProcedureEnv>>, TableProcedureInterface

@InterfaceAudience.Private
public class ReopenTableRegionsProcedure
extends AbstractStateMachineTableProcedure<MasterProcedureProtos.ReopenTableRegionsState>

Used for reopening the regions for a table.

Currently we use MoveRegionProcedure to reopen regions.

Constructor Detail

ReopenTableRegionsProcedure

public ReopenTableRegionsProcedure()

ReopenTableRegionsProcedure

public ReopenTableRegionsProcedure(TableName tableName)

Method Detail

getTableName

public TableName getTableName()

Specified by:

getTableName in interface TableProcedureInterface

Specified by:

getTableName in class AbstractStateMachineTableProcedure<MasterProcedureProtos.ReopenTableRegionsState>

Returns:

the name of the table the procedure is operating on

getTableOperationType

public TableProcedureInterface.TableOperationType getTableOperationType()

Description copied from interface: 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.

Specified by:

getTableOperationType in interface TableProcedureInterface

Specified by:

getTableOperationType in class AbstractStateMachineTableProcedure<MasterProcedureProtos.ReopenTableRegionsState>

Returns:

the operation type that the procedure is executing.

executeFromState
