Method Details
-
getServerName
Description copied from interface:ServerProcedureInterface
Returns Name of this server instance.- Specified by:
getServerName
in interfaceServerProcedureInterface
-
hasMetaTableRegion
Description copied from interface:ServerProcedureInterface
Returns True if this server has an hbase:meta table region.- Specified by:
hasMetaTableRegion
in interfaceServerProcedureInterface
-
getServerOperationType
Description copied from interface:ServerProcedureInterface
Given an operation type we can take decisions about what to do with pending operations. e.g. if we get a crash handler and we have some assignment operation pending we can abort those operations.- Specified by:
getServerOperationType
in interfaceServerProcedureInterface
- Returns:
- the operation type that the procedure is executing.
-
addMissingQueues
- Throws:
ReplicationException
-
claimQueues
private StateMachineProcedure.Flow claimQueues(MasterProcedureEnv env) throws ReplicationException, IOException - Throws:
ReplicationException
IOException
-
shouldSkip
- Throws:
IOException
-
removeQueues
- Throws:
ReplicationException
IOException
-
executeFromState
protected StateMachineProcedure.Flow executeFromState(MasterProcedureEnv env, org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.AssignReplicationQueuesState 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.AssignReplicationQueuesState> 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.AssignReplicationQueuesState 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.AssignReplicationQueuesState> state
- state to rollback- Throws:
IOException
- temporary failure, the rollback will retry laterInterruptedException
-
getState
protected org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.AssignReplicationQueuesState 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.AssignReplicationQueuesState> - 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.AssignReplicationQueuesState 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.AssignReplicationQueuesState> - 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.AssignReplicationQueuesState 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.AssignReplicationQueuesState> - Returns:
- the initial state enum object
-
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.AssignReplicationQueuesState> - 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.AssignReplicationQueuesState> - Parameters:
serializer
- contains the serialized state- Throws:
IOException
