Method Detail

initializeOp

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

Description copied from class: Operator

Operator specific initialization.

Throws:

HiveException

closeOp

public void closeOp(boolean aborted)
             throws HiveException

Description copied from class: CommonJoinOperator

All done.

Overrides:

closeOp in class MapJoinOperator

Throws:

HiveException

processOp

public void processOp(Object row,
                      int tag)
               throws HiveException

Description copied from class: Operator

Process the row.

Overrides:
