processOp
public void processOp(Object row,
int tag)
throws HiveException
- Description copied from class:
Operator
- Process the row.
- Specified by:
processOp
in class Operator<HashTableSinkDesc>
- Parameters:
row
- The object representing the row.tag
- The tag of the row usually means which parent this row comes from.

public 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.
- Throws:
HiveException
