Class AbstractStateMachineNamespaceProcedure<TState>

java.lang.Object

<any>

org.apache.hadoop.hbase.master.procedure.AbstractStateMachineNamespaceProcedure<TState>

All Implemented Interfaces:

TableProcedureInterface

Direct Known Subclasses:

CreateNamespaceProcedure, DeleteNamespaceProcedure, ModifyNamespaceProcedure

public abstract class AbstractStateMachineNamespaceProcedure<TState>
extends <any>
implements TableProcedureInterface

Base class for all the Namespace procedures that want to use a StateMachineProcedure. It provide some basic helpers like basic locking and basic toStringClassDetails().

Method Detail

getNamespaceName

protected abstract java.lang.String getNamespaceName()

getTableName

public TableName getTableName()

Specified by:

getTableName in interface TableProcedureInterface

Returns:

the name of the table the procedure is operating on

getTableOperationType

public abstract 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

Returns:

the operation type that the procedure is executing.

toStringClassDetails

public void toStringClassDetails(java.lang.StringBuilder sb)

acquireLock

protected LockState acquireLock(MasterProcedureEnv env)

releaseLock

protected void releaseLock(MasterProcedureEnv env)

releaseSyncLatch

protected void releaseSyncLatch()
