protected void rollback(MasterProcedureEnv env)
                 throws IOException,
                        InterruptedException

Specified by:

rollback in class Procedure<MasterProcedureEnv>

Throws:

IOException

InterruptedException

abort

protected boolean abort(MasterProcedureEnv env)

Specified by:

abort in class Procedure<MasterProcedureEnv>

serializeStateData

protected void serializeStateData(ProcedureStateSerializer serializer)
                           throws IOException

Specified by:

serializeStateData in class Procedure<MasterProcedureEnv>

Throws:

IOException

deserializeStateData

protected void deserializeStateData(ProcedureStateSerializer serializer)
                             throws IOException

Specified by:

deserializeStateData in class Procedure<MasterProcedureEnv>

Throws:

IOException

remoteCallBuild

public Optional<RemoteProcedureDispatcher.RemoteOperation> remoteCallBuild(MasterProcedureEnv masterProcedureEnv,
                                                                           ServerName remote)

getServerName

public ServerName getServerName()

Specified by:

getServerName in interface ServerProcedureInterface

Returns:

Name of this server instance.

hasMetaTableRegion

public boolean hasMetaTableRegion()

Specified by:

hasMetaTableRegion in interface ServerProcedureInterface

Returns:

True if this server has an hbase:meta table region.

getServerOperationType

public ServerProcedureInterface.ServerOperationType 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 interface ServerProcedureInterface

Returns:

the operation type that the procedure is executing.

complete

protected void complete(MasterProcedureEnv env,
                        Throwable error)

Specified by:

complete in class ServerRemoteProcedure

toStringClassDetails

public void toStringClassDetails(StringBuilder sb)

Overrides:
