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 AppMasterEventOperator

Throws:

HiveException

process

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

Description copied from class: Operator

Process the row.

Overrides:

process in class AppMasterEventOperator

Parameters:
