Modifier and Type | Method and Description |
---|---|
protected Procedure.LockState |
acquireLock(MasterProcedureEnv env)
The user should override this method if they need a lock on an Entity.
|
protected void |
afterReplay(MasterProcedureEnv env)
Called when the procedure is ready to be added to the queue after the loading/replay operation.
|
private FlushRegionProcedure[] |
createFlushRegionProcedures(MasterProcedureEnv env) |
protected void |
deserializeStateData(ProcedureStateSerializer serializer)
Called on store load to allow the user to decode the previously serialized state.
|
protected StateMachineProcedure.Flow |
executeFromState(MasterProcedureEnv env,
org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.FlushTableState state)
called to perform a single step of the specified 'state' of the procedure
|
protected org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.FlushTableState |
getInitialState()
Return the initial state object that will be used for the first call to executeFromState().
|
protected org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.FlushTableState |
getState(int stateId)
Convert an ordinal (or state id) to an Enum (or more descriptive) state object.
|
protected int |
getStateId(org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.FlushTableState state)
Convert the Enum (or more descriptive) state object to an ordinal (or state id).
|
TableName |
getTableName()
Returns the name of the table the procedure is operating on
|
TableProcedureInterface.TableOperationType |
getTableOperationType()
Given an operation type we can take decisions about what to do with pending operations.
|
protected void |
releaseLock(MasterProcedureEnv env)
The user should override this method, and release lock if necessary.
|
protected void |
rollbackState(MasterProcedureEnv env,
org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.FlushTableState state)
called to perform the rollback of the specified state
|
protected void |
serializeStateData(ProcedureStateSerializer serializer)
The user-level code of the procedure may have some state to persist (e.g.
|
void |
toStringClassDetails(StringBuilder builder)
Extend the toString() information with the procedure details e.g.

protected Procedure.LockState acquireLock(MasterProcedureEnv env)
Procedure
Procedure.execute(Object)
. It calls Procedure.releaseLock(Object)
after the call to
execute.
If you need to hold the lock for the life of the Procedure -- i.e. you do not want any other
Procedure interfering while this Procedure is running, see Procedure.holdLock(Object)
.
Example: in our Master we can execute request in parallel for different tables. We can create
t1 and create t2 and these creates can be executed at the same time. Anything else on t1/t2 is
queued waiting that specific table create to happen.
There are 3 LockState:
