executeFromState
protected StateMachineProcedure.Flow executeFromState(MasterProcedureEnv env, org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MigrateReplicationQueueFromZkToTableState 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 classStateMachineProcedure<MasterProcedureEnv,
org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MigrateReplicationQueueFromZkToTableState> 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
-
setTimeoutFailure
Description copied from class:Procedure
Called by the ProcedureExecutor when the timeout set by setTimeout() is expired. Another usage for this method is to implement retrying. A procedure can set the state toWAITING_TIMEOUT
by callingsetState
method, and throw aProcedureSuspendedException
to halt the execution of the procedure, and do not forget a callProcedure.setTimeout(int)
method to set the timeout. And you should also override this method to wake up the procedure, and also return false to tell the ProcedureExecutor that the timeout event has been handled.- Overrides:
setTimeoutFailure
in classProcedure<MasterProcedureEnv>
- Returns:
- true to let the framework handle the timeout as abort, false in case the procedure handled the timeout itself.
-
rollbackState
protected void rollbackState(MasterProcedureEnv env, org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MigrateReplicationQueueFromZkToTableState state) throws IOException, InterruptedException Description copied from class:StateMachineProcedure
called to perform the rollback of the specified state- Specified by:
rollbackState
in classStateMachineProcedure<MasterProcedureEnv,
org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MigrateReplicationQueueFromZkToTableState> state
- state to rollback- Throws:
IOException
- temporary failure, the rollback will retry laterInterruptedException
-
getState
protected org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MigrateReplicationQueueFromZkToTableState 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 classStateMachineProcedure<MasterProcedureEnv,
org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MigrateReplicationQueueFromZkToTableState> - 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.MigrateReplicationQueueFromZkToTableState state) Description copied from class:StateMachineProcedure
Convert the Enum (or more descriptive) state object to an ordinal (or state id).- Specified by:
getStateId
in classStateMachineProcedure<MasterProcedureEnv,
org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MigrateReplicationQueueFromZkToTableState> - 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.MigrateReplicationQueueFromZkToTableState 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 classStateMachineProcedure<MasterProcedureEnv,
org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MigrateReplicationQueueFromZkToTableState> - Returns:
- the initial state enum object
-
afterReplay
Description copied from class:Procedure
Called when the procedure is ready to be added to the queue after the loading/replay operation.- Overrides:
afterReplay
in classProcedure<MasterProcedureEnv>
-
serializeStateData
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 classStateMachineProcedure<MasterProcedureEnv,
org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MigrateReplicationQueueFromZkToTableState> - Parameters:
serializer
- stores the serializable state- Throws:
IOException
-
deserializeStateData
Description copied from class:Procedure
Called on store load to allow the user to decode the previously serialized state.- Overrides:
deserializeStateData
in classStateMachineProcedure<MasterProcedureEnv,
org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.MigrateReplicationQueueFromZkToTableState> - Parameters:
serializer
- contains the serialized state- Throws:
IOException
