Modifier and Type | Method and Description |
---|---|
boolean |
abort(MasterProcedureEnv env)
The abort() call is asynchronous and each procedure must decide how to deal with it, if they
want to be abortable.
|
private void |
addRegionsToInMemoryStates(List<RegionInfo> regionInfos,
MasterProcedureEnv env,
int regionReplication)
Add regions to in-memory states
|
private void |
deleteRegionsFromInMemoryStates(List<RegionInfo> regionInfos,
MasterProcedureEnv env,
int regionReplication)
Delete regions from in-memory states
|
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.RestoreSnapshotState state)
called to perform a single step of the specified 'state' of the procedure
|
protected org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.RestoreSnapshotState |
getInitialState()
Return the initial state object that will be used for the first call to executeFromState().
|
private MonitoredTask |
getMonitorStatus()
Set up monitor status if it is not created.
|
boolean |
getRestoreAcl()
Exposed for Testing: HBASE-26462
|
protected org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.RestoreSnapshotState |
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.RestoreSnapshotState 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 boolean |
isRollbackSupported(org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.RestoreSnapshotState state)
Used by the default implementation of abort() to know if the current state can be aborted and
rollback can be triggered.
|
private void |
prepareRestore(MasterProcedureEnv env)
Action before any real action of restoring from snapshot.
|
private void |
restoreSnapshot(MasterProcedureEnv env)
Execute the on-disk Restore
|
private void |
restoreSnapshotAcl(MasterProcedureEnv env) |
protected void |
rollbackState(MasterProcedureEnv env,
org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.RestoreSnapshotState 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 sb)
Extend the toString() information with the procedure details e.g.
|
private void |
updateMETA(MasterProcedureEnv env)
Apply changes to hbase:meta
|
private void |
updateTableDescriptor(MasterProcedureEnv env)
Update descriptor
