Kryo ctor.

VectorFileSinkArrowOperator

public VectorFileSinkArrowOperator(CompilationOpContext ctx)

Method Detail

getInputVectorizationContext

public VectorizationContext getInputVectorizationContext()

Specified by:

getInputVectorizationContext in interface VectorizationOperator

initializeOp

protected void initializeOp(org.apache.hadoop.conf.Configuration hconf)
                     throws HiveException

Description copied from class: Operator

Operator specific initialization.

Overrides:

initializeOp in class Operator<FileSinkDesc>

Throws:

HiveException

process

public void process(Object data,
                    int tag)
             throws HiveException

Description copied from class: Operator

Process the row.

Specified by:

process in class Operator<FileSinkDesc>

Parameters:

data - The object representing the row.

tag - The tag of the row usually means which parent this row comes from. Rows with the same tag should have exactly the same rowInspector all the time.

Throws:

HiveException

closeOp

protected void closeOp(boolean abort)
                throws HiveException

Description copied from class: Operator

Operator specific close routine. Operators which inherents this class should overwrite this funtion for their specific cleanup routine.

Overrides:

closeOp in class Operator<FileSinkDesc>

Throws:

HiveException

getVectorDesc

public VectorDesc getVectorDesc()

Specified by:

getVectorDesc in interface VectorizationOperator

getType

public OperatorType getType()

Description copied from class: Operator

Return the type of the specific operator among the types in OperatorType.

Specified by:

getType in class Operator<FileSinkDesc>

Returns:

OperatorType.*
