java.lang.Object

org.apache.hadoop.hbase.procedure2.Procedure<TEnvironment>

org.apache.hadoop.hbase.procedure2.StateMachineProcedure<MasterProcedureEnv,TState>

org.apache.hadoop.hbase.master.procedure.AbstractStateMachineTableProcedure<MasterProcedureProtos.InitMetaState>

org.apache.hadoop.hbase.master.procedure.InitMetaProcedure

All Implemented Interfaces:

Comparable<Procedure<MasterProcedureEnv>>, TableProcedureInterface

@InterfaceAudience.Private
public class InitMetaProcedure
extends AbstractStateMachineTableProcedure<MasterProcedureProtos.InitMetaState>

This procedure is used to initialize meta table for a new hbase deploy. It will just schedule an TransitRegionStateProcedure to assign meta.

Constructor Detail

InitMetaProcedure

public InitMetaProcedure()

Method Detail

getTableName

public TableName getTableName()

Specified by:

getTableName in interface TableProcedureInterface

Specified by:

getTableName in class AbstractStateMachineTableProcedure<MasterProcedureProtos.InitMetaState>

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.InitMetaState>

Returns:

the operation type that the procedure is executing.
