Deprecated.

Method Details

executeFromState

protected StateMachineProcedure.Flow executeFromState(MasterProcedureEnv env,
 org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MoveRegionState state)
                                               throws InterruptedException

Deprecated.

Description copied from class: StateMachineProcedure

called to perform a single step of the specified 'state' of the procedure

Specified by:

executeFromState in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MoveRegionState>

state - state to execute

Returns:

Flow.NO_MORE_STATE if the procedure is completed, Flow.HAS_MORE_STATE if there is another step.

Throws:

InterruptedException

rollbackState

protected void rollbackState(MasterProcedureEnv env,
 org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MoveRegionState state)
                      throws IOException

Deprecated.

Description copied from class: StateMachineProcedure

called to perform the rollback of the specified state

Specified by:

rollbackState in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MoveRegionState>

state - state to rollback

Throws:

IOException - temporary failure, the rollback will retry later

abort

public boolean abort(MasterProcedureEnv env)

Deprecated.

Description copied from class: Procedure

The abort() call is asynchronous and each procedure must decide how to deal with it, if they want to be abortable. The simplest implementation is to have an AtomicBoolean set in the abort() method and then the execute() will check if the abort flag is set or not. abort() may be called multiple times from the client, so the implementation must be idempotent.

NOTE: abort() is not like Thread.interrupt(). It is just a notification that allows the procedure implementor abort.

Overrides:

abort in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MoveRegionState>

toStringClassDetails

public void toStringClassDetails(StringBuilder sb)

Deprecated.

Description copied from class: Procedure

Extend the toString() information with the procedure details e.g. className and parameters

Overrides:

toStringClassDetails in class AbstractStateMachineRegionProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MoveRegionState>

Parameters:

sb - the string builder to use to append the proc specific information

getInitialState

protected org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MoveRegionState getInitialState()

Deprecated.

Description copied from class: StateMachineProcedure

Return the initial state object that will be used for the first call to executeFromState().

Specified by:

getInitialState in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MoveRegionState>

Returns:

the initial state enum object

getStateId

protected int getStateId(org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MoveRegionState state)

Deprecated.

Description copied from class: StateMachineProcedure

Convert the Enum (or more descriptive) state object to an ordinal (or state id).

Specified by:

getStateId in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MoveRegionState>

Parameters:

state - the state enum object

Returns:

stateId the ordinal() of the state enum (or state id)

getState

protected org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MoveRegionState getState(int stateId)

Deprecated.

Description copied from class: StateMachineProcedure

Convert an ordinal (or state id) to an Enum (or more descriptive) state object.

Specified by:

getState in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MoveRegionState>

Parameters:

stateId - the ordinal() of the state enum (or state id)

Returns:

the state enum object

getTableName

public TableName getTableName()

Deprecated.

Description copied from interface: TableProcedureInterface

Returns the name of the table the procedure is operating on

Specified by:

getTableName in interface TableProcedureInterface

Overrides:

getTableName in class AbstractStateMachineRegionProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MoveRegionState>

getTableOperationType

public TableProcedureInterface.TableOperationType getTableOperationType()

Deprecated.

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 AbstractStateMachineRegionProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MoveRegionState>

Returns:

the operation type that the procedure is executing.

serializeStateData

protected void serializeStateData(ProcedureStateSerializer serializer)
                           throws IOException

Deprecated.

Description copied from class: Procedure

The user-level code of the procedure may have some state to persist (e.g. input arguments or current position in the processing state) to be able to resume on failure.

Overrides:

serializeStateData in class AbstractStateMachineRegionProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MoveRegionState>

Parameters:

serializer - stores the serializable state

Throws:

IOException

deserializeStateData

protected void deserializeStateData(ProcedureStateSerializer serializer)
                             throws IOException

Deprecated.

Description copied from class: Procedure

Called on store load to allow the user to decode the previously serialized state.

Overrides:

deserializeStateData in class AbstractStateMachineRegionProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MoveRegionState>

Parameters:

serializer - contains the serialized state

Throws:

IOException
