Method Detail

executeFromState

protected StateMachineProcedure.Flow executeFromState(MasterProcedureEnv env,
                                          org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.TruncateTableState state)

Specified by:

executeFromState in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.TruncateTableState>

rollbackState

protected void rollbackState(MasterProcedureEnv env,
                 org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.TruncateTableState state)

Specified by:

rollbackState in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.TruncateTableState>

getState

protected org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.TruncateTableState getState(int stateId)

Specified by:

getState in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.TruncateTableState>

getStateId

protected int getStateId(org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.TruncateTableState state)

Specified by:

getStateId in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.TruncateTableState>

getInitialState

protected org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.TruncateTableState getInitialState()

Specified by:

getInitialState in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.TruncateTableState>

getTableName

public TableName getTableName()

Specified by:

getTableName in interface TableProcedureInterface

Returns:

the name of the table the procedure is operating on

getTableOperationType

public TableProcedureInterface.TableOperationType getTableOperationType()

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.

Specified by:

getTableOperationType in interface TableProcedureInterface

Returns:

the operation type that the procedure is executing.

abort

public boolean abort(MasterProcedureEnv env)

Specified by:

abort in class Procedure<MasterProcedureEnv>

acquireLock

protected boolean acquireLock(MasterProcedureEnv env)

Overrides:

acquireLock in class Procedure<MasterProcedureEnv>

releaseLock

protected void releaseLock(MasterProcedureEnv env)

Overrides:

releaseLock in class Procedure<MasterProcedureEnv>

toStringClassDetails

public void toStringClassDetails(StringBuilder sb)

Overrides:

toStringClassDetails in class Procedure<MasterProcedureEnv>

serializeStateData

public void serializeStateData(OutputStream stream)
                        throws IOException

Overrides:

serializeStateData in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.TruncateTableState>

Throws:

IOException

deserializeStateData

public void deserializeStateData(InputStream stream)
                          throws IOException

Overrides:

deserializeStateData in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.TruncateTableState>

Throws:

IOException
