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 Operator<SparkHashTableSinkDesc>

Throws:

HiveException

process

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

Description copied from class: Operator

Process the row.

Specified by:

process in class Operator<SparkHashTableSinkDesc>

Parameters:

row - 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

closeOp

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.

Overrides:

closeOp in class Operator<SparkHashTableSinkDesc>

Throws:

HiveException

flushToFile

protected void flushToFile(MapJoinPersistableTableContainer tableContainer,
               byte tag)
                    throws Exception

Throws:

Exception

setTag

public void setTag(byte tag)

getName

public String getName()

Implements the getName function for the Node Interface.

Specified by:

getName in interface Node

Overrides:

getName in class Operator<SparkHashTableSinkDesc>

Returns:

the name of the operator

getType

public OperatorType getType()

Description copied from class: Operator

Return the type of the specific operator among the types in OperatorType.

Specified by:

getType in class Operator<SparkHashTableSinkDesc>

Returns:

OperatorType.*
