Method Detail

initializeOp

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

Description copied from class: Operator

Operator specific initialization.

Overrides:

initializeOp in class MapJoinOperator

Throws:

HiveException

internalForward

protected void internalForward(Object row,
                               ObjectInspector outputOI)

'forwards' the (row-mode) record into the (vectorized) output batch

Overrides:

internalForward in class CommonJoinOperator<MapJoinDesc>

Throws:

HiveException

closeOp

public void closeOp(boolean aborted)
             throws HiveException

Description copied from class: CommonJoinOperator

All done.

Overrides:
