Method Details

getGlobalId

public String getGlobalId()

Specified by:

getGlobalId in interface GlobalProcedureInterface

migrate

private void migrate(MasterProcedureEnv env)
              throws IOException

Throws:

IOException

executeFromState

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

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.MigrateNamespaceTableProcedureState>

state - state to execute

Returns:

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

Throws:

ProcedureSuspendedException

ProcedureYieldException

InterruptedException

rollbackState

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

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.MigrateNamespaceTableProcedureState>

state - state to rollback

Throws:

IOException - temporary failure, the rollback will retry later

InterruptedException

getState

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

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.MigrateNamespaceTableProcedureState>

Parameters:

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

Returns:

the state enum object

getStateId

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

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.MigrateNamespaceTableProcedureState>

Parameters:

state - the state enum object

Returns:

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

getInitialState

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

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.MigrateNamespaceTableProcedureState>

Returns:

the initial state enum object

completionCleanup

protected void completionCleanup(MasterProcedureEnv env)

Description copied from class: Procedure

Called when the procedure is marked as completed (success or rollback). The procedure implementor may use this method to cleanup in-memory states. This operation will not be retried on failure. If a procedure took a lock, it will have been released when this method runs.

Overrides:

completionCleanup in class Procedure<MasterProcedureEnv>
