Method Detail

initializeOp

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

Description copied from class: Operator

Operator specific initialization.

Overrides:

initializeOp in class ReduceSinkOperator

Throws:

HiveException

process

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

Description copied from class: Operator

Process the row.

Overrides:

process in class ReduceSinkOperator

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
