All Implemented Interfaces:

Serializable, Cloneable, VectorizationContextRegion, Node

public class VectorMapJoinOuterFilteredOperator
extends VectorMapJoinBaseOperator

This is the *NON-NATIVE* vector map join operator for just LEFT OUTER JOIN and filtered. It is a row pass-thru so that super MapJoinOperator can do the outer join filtering properly.

initializeOp

public Collection<Future<?>> initializeOp(org.apache.hadoop.conf.Configuration hconf)
                                   throws HiveException

Description copied from class: Operator

Operator specific initialization.

Overrides:

initializeOp in class VectorMapJoinBaseOperator

Throws:

HiveException

process

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

Description copied from class: Operator

Process the row.

Overrides:

process in class MapJoinOperator

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
