Method Detail

initializeOp

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

Description copied from class: Operator

Operator specific initialization.

Overrides:

initializeOp in class SelectOperator

Throws:

HiveException

processOp

public void processOp(Object row,
                      int tag)
