UnassignProcedure

public UnassignProcedure()

Deprecated.

Method Details

getTableOperationType

public TableProcedureInterface.TableOperationType getTableOperationType()

Deprecated.

Description copied from interface: TableProcedureInterface

Given an operation type we can take decisions about what to do with pending operations. e.g. if we get a delete and we have some table operation pending (e.g. add column) we can abort those operations.

Returns:

the operation type that the procedure is executing.

isRollbackSupported

protected boolean isRollbackSupported(org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.RegionTransitionState state)

Deprecated.

Specified by:

isRollbackSupported in class RegionTransitionProcedure

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.

Specified by:

serializeStateData in class Procedure<MasterProcedureEnv>

Parameters:

serializer - stores the serializable state

Throws:

IOException

deserializeStateData

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.

Specified by:

deserializeStateData in class Procedure<MasterProcedureEnv>

Parameters:

serializer - contains the serialized state

Throws:

IOException

startTransition

protected boolean startTransition(MasterProcedureEnv env,
 RegionStateNode regionNode)

Deprecated.

Specified by:

startTransition in class RegionTransitionProcedure

updateTransition

protected boolean updateTransition(MasterProcedureEnv env,
 RegionStateNode regionNode)
                            throws IOException

Deprecated.

Specified by:

updateTransition in class RegionTransitionProcedure

Throws:

IOException

finishTransition

protected void finishTransition(MasterProcedureEnv env,
 RegionStateNode regionNode)
                         throws IOException

Deprecated.

Specified by:

finishTransition in class RegionTransitionProcedure

Throws:

IOException

remoteCallBuild

public Optional<RemoteProcedureDispatcher.RemoteOperation> remoteCallBuild(MasterProcedureEnv env,
 ServerName serverName)

Deprecated.

Description copied from interface: RemoteProcedureDispatcher.RemoteProcedure

For building the remote operation. May be empty if no need to send remote call. Usually, this means the RemoteProcedure has been finished already. This is possible, as we may have already sent the procedure to RS but then the rpc connection is broken so the executeProcedures call fails, but the RS does receive the procedure and execute it and then report back, before we retry again.

Specified by:

remoteCallBuild in interface RemoteProcedureDispatcher.RemoteProcedure<MasterProcedureEnv,ServerName>

Specified by:

remoteCallBuild in class RegionTransitionProcedure

reportTransition

protected void reportTransition(MasterProcedureEnv env,
 RegionStateNode regionNode,
 org.apache.hadoop.hbase.shaded.protobuf.generated.RegionServerStatusProtos.RegionStateTransition.TransitionCode code,
 long seqId)
                         throws UnexpectedStateException

Deprecated.

Specified by:

reportTransition in class RegionTransitionProcedure

Throws:

UnexpectedStateException

remoteCallFailed

protected boolean remoteCallFailed(MasterProcedureEnv env,
 RegionStateNode regionNode,
 IOException exception)

Deprecated.

Returns If true, we will re-wake up this procedure; if false, the procedure stays suspended.

Specified by:

remoteCallFailed in class RegionTransitionProcedure

toStringClassDetails

public 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 RegionTransitionProcedure

Parameters:

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

getProcedureMetrics

protected ProcedureMetrics getProcedureMetrics(MasterProcedureEnv env)

Deprecated.

Description copied from class: Procedure

Override this method to provide procedure specific counters for submitted count, failed count and time histogram.

Overrides:

getProcedureMetrics in class Procedure<MasterProcedureEnv>

Parameters:

env - The environment passed to the procedure executor

Returns:

Container object for procedure related metric
