All Implemented Interfaces:

Comparable<Procedure<MasterProcedureEnv>>, MetaProcedureInterface

@Deprecated

public class RecoverMetaProcedure
extends StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.RecoverMetaState>
implements MetaProcedureInterface

Deprecated.

Do not use any more, leave it here only for compatible. The recovery work will be done in ServerCrashProcedure directly, and the initial work for meta table will be done by InitMetaProcedure.

Leave here only for checking if we can successfully start the master.

Method Details

executeFromState

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

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.RecoverMetaState recoverMetaState)
                      throws IOException,
InterruptedException

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.RecoverMetaState>

recoverMetaState - state to rollback

Throws:

IOException - temporary failure, the rollback will retry later

InterruptedException

getState

protected org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.RecoverMetaState 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.RecoverMetaState>

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.RecoverMetaState recoverMetaState)

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.RecoverMetaState>

Parameters:

recoverMetaState - 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.RecoverMetaState 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.RecoverMetaState>

Returns:

the initial state enum object

toStringClassDetails

protected 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 Procedure<MasterProcedureEnv>

Parameters:

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

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 StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.RecoverMetaState>

Parameters:

serializer - stores the serializable state

Throws:

IOException

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 StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.RecoverMetaState>

Parameters:

serializer - contains the serialized state

Throws:

IOException
